Maternity Leave vs Shared Parental Leave — Key Differences Explained (CIPD 5OS01 AC 2.1)
Why Trust This Assignment?
- AC 2.1CIPD 5OS01requires the student to explain the differences between maternity leave and shared parental leave — two distinct statutory entitlements governed by separate legislative instruments: the Maternity and Paternity Leave Regulations 1999 and the Shared Parental Leave Regulations 2014. These are not variations of the same right. Maternity leave is a right held exclusively by the mother, activated automatically on notification of pregnancy. Shared Parental Leave is a separate entitlement that can only be unlocked when the mother actively curtails her maternity leave and both parents independently satisfy their own eligibility tests. Understanding this structural difference is the foundation of any correct AC 2.1 answer at CIPD Level 5.

AC 2.1 — What the Assessment Criterion Requires
AC 2.1 of the CIPD 5OS01 Specialist Employment Law unit requires the student to explain the legal and practical differences between maternity leave and shared parental leave. The typical scenario positions the student as an HR adviser responding to a query from a pregnant employee or their line manager about which entitlements apply and how the two regimes differ. A pass-level answer lists the differences in general terms. A distinction-level answer cites governing regulations by full title, states specific statutory values (£184.03/week; 52 weeks; 50 weeks; 8-week notice per block), and addresses the HR compliance implications of running both leave types within the same workforce.
The assessment criterion operates within the 5OS01 Specialist Employment Law unit of the CIPD Level 5 Associate Diploma in People Management. At distinction level, the answer must demonstrate that the student understands not only what the entitlements are, but why the legislative design choices produce different administrative and financial outcomes for employers and employees. The financial gap between Statutory Maternity Pay and Statutory Shared Parental Pay — the 90% average weekly earnings period present in SMP but absent from ShPP — is the central analytical point for AC 2.1 and must feature in any answer above pass level.
Maternity Leave — Eligibility, Duration and Statutory Pay
Maternity leave entitles an employee to up to 52 weeks of leave from work following the birth or expected birth of a child, under the Maternity and Paternity Leave Regulations 1999, made under the authority of the Employment Rights Act 1996 s.71–73. The entitlement applies to employees only: workers without employee status do not qualify for statutory maternity leave, though they may qualify for Statutory Maternity Pay separately if they meet the earnings and service conditions in the Social Security Contributions and Benefits Act 1992.
Eligibility for maternity leave requires employee status and 26 weeks of continuous employment with the same employer by the 15th week before the Expected Week of Childbirth (EWC). This is sometimes described as the “qualifying week.” An employee who has fewer than 26 weeks of service by that point does not qualify for statutory maternity leave but may still qualify for Statutory Maternity Pay if they meet the earnings threshold.
For employers managing staff through pregnancy, the maternity leave employer guide covers the full range of obligations including risk assessments, suitable alternative employment during suspension, and Keeping In Touch day management.
Ordinary Maternity Leave and Additional Maternity Leave
Maternity leave divides into two consecutive phases under the Maternity and Paternity Leave Regulations 1999. Ordinary Maternity Leave (OML) covers the first 26 weeks and is available to all employees regardless of their length of service. Additional Maternity Leave (AML) covers the second 26 weeks, immediately following OML, bringing the total entitlement to 52 weeks.
The return-to-work rights differ between the two phases, and this distinction matters for HR compliance. A woman who returns at any point during or at the end of OML has the right to return to the same job she held before her leave — on the same terms and conditions. A woman who takes all or part of AML has the right to return to the same job where it is reasonably practicable to offer it; if not, she is entitled to a suitable and appropriate alternative. This distinction is tested at distinction level in CIPD AC 2.1 answers because it reflects a real compliance risk: an employer who fails to offer the correct return pathway risks an unfair dismissal or detriment claim under the ERA 1996.
The first two weeks following the birth are compulsory maternity leave under Regulation 8 of the Maternity and Paternity Leave Regulations 1999. An employer cannot permit an employee to return to work during this compulsory period. For employees who work in a factory, the compulsory period extends to four weeks.
Statutory Maternity Pay — Rate and Duration
Statutory Maternity Pay (SMP) is payable for up to 39 weeks of the 52-week leave entitlement under the Social Security Contributions and Benefits Act 1992. The rate structure divides into two stages. For weeks 1 to 6, SMP is payable at 90% of the employee’s average weekly earnings (AWE) with no upper ceiling. For weeks 7 to 39, SMP is payable at the flat rate of £184.03 per week (2024/25 rate, subject to annual uprating each April) or 90% of AWE if that figure is lower. Weeks 40 to 52, where taken, are unpaid.
Eligibility for SMP requires that the employee has 26 weeks of continuous employment by the qualifying week and earns at or above the Lower Earnings Limit (£123/week for 2024/25). An employee who qualifies for maternity leave but not SMP — because she has been employed for fewer than 26 weeks or earns below the LEL — may qualify for Maternity Allowance through the Department for Work and Pensions.
The 90% of AWE period in weeks 1 to 6 is the element that makes SMP financially more valuable than Statutory Shared Parental Pay in the early weeks of leave. For an employee earning £40,000 per year, the average weekly earnings figure is approximately £769/week, making the SMP rate in weeks 1 to 6 approximately £692/week — nearly four times the ShPP flat rate. This gap is the primary financial comparison for AC 2.1 and is the reason why ShPL take-up by partners remains significantly below its potential.
Shared Parental Leave — Eligibility, Duration and Statutory Pay
Shared Parental Leave requires both parents to satisfy separate eligibility tests before either can access the entitlement. This dual-test structure distinguishes ShPL from maternity leave, which is a single-test entitlement. The governing legislation is the Shared Parental Leave Regulations 2014, made under the Work and Families Act 2006.
ShPL became available for babies born or adopted on or after 5 April 2015. Its purpose is to enable greater flexibility in how parents share childcare in the first year of a child’s life, moving away from the model where the mother takes all 52 weeks. In practice, take-up by partners has remained low — CIPD (2022) research shows fewer than 5% of eligible fathers and partners use ShPL — with the financial gap between SMP and ShPP cited as the primary deterrent.
For the full employer guide to shared parental leave UK, including block booking procedures, curtailment notice requirements, and SPLIT day management, the dedicated employer guide covers the operational process in full.
The Dual Eligibility Test — What Makes ShPL More Complex
Shared Parental Leave requires both parents to independently satisfy their own eligibility test. If either parent fails their test, neither parent can access ShPL. This is a fundamental structural difference from maternity leave, where a single eligibility test applies to the mother alone.
The mother’s eligibility test requires three conditions: she must qualify for statutory maternity leave or for Statutory Maternity Pay (or Maternity Allowance); she must share the caring responsibility for the child with her partner; and she must give a valid curtailment notice to her employer specifying the date on which she will end her maternity leave. Without the curtailment notice, ShPL cannot begin for either parent.
The partner’s eligibility test requires that the partner has been employed by the same employer for at least 26 continuous weeks by the 15th week before the Expected Week of Childbirth; earns at or above the Lower Earnings Limit (£123/week for 2024/25); and is living with the child and the mother at the time they take ShPL. The partner must also provide their employer with written confirmation from the mother that she has curtailed her maternity leave.
This dual structure generates significantly greater administrative complexity than the single-test maternity leave eligibility check. HR teams must verify two separate eligibility conditions, process the curtailment notice, and issue confirmation to both the mother and the partner before any ShPL entitlement is activated.
Statutory Shared Parental Pay — How It Differs from SMP
Statutory Shared Parental Pay (ShPP) is governed by the Statutory Shared Parental Pay (General) Regulations 2014. ShPP pays at a flat rate of £184.03 per week (2024/25) or 90% of average weekly earnings if that figure is lower — for the entire ShPP period. There is no enhanced 90% period for the first weeks of ShPP, unlike SMP which pays 90% of AWE for the first 6 weeks.
For an employee earning £40,000 per year, the difference is stark: SMP in weeks 1 to 6 would be approximately £692/week, while ShPP from week 1 is £184.03/week — a weekly gap of approximately £508. Over six weeks, a partner who takes ShPL instead of the mother continuing SMP faces a household income reduction of approximately £3,050 in that early period alone.
Up to 37 weeks of ShPP are available to share between both parents (compared to 39 weeks of SMP), because the compulsory maternity leave period already accounts for 2 weeks of the SMP entitlement.
Key Differences Between Maternity Leave and Shared Parental Leave
Maternity leave differs from Shared Parental Leave in six principal respects: governing legislation, eligibility structure, available duration, statutory pay rate, flexibility, and notice requirements. The following comparison covers each dimension with specific statutory values.
| Dimension | Maternity Leave | Shared Parental Leave |
|---|---|---|
| Governing legislation | Maternity and Paternity Leave Regulations 1999; Employment Rights Act 1996 s.71–73 | Shared Parental Leave Regulations 2014; Work and Families Act 2006 |
| Eligibility | Employee with 26 weeks service by week 15 before EWC (single test) | Both parents must independently satisfy separate eligibility tests |
| Duration | 52 weeks total (OML 26 weeks + AML 26 weeks) | Up to 50 weeks available to share between both parents |
| Statutory pay rate | SMP: 90% AWE for weeks 1–6 (no cap); £184.03/week for weeks 7–39 (2024/25) | ShPP: £184.03/week flat rate from week 1 — no enhanced 90% period |
| Flexibility | Continuous block; up to 10 Keeping In Touch (KIT) days permitted | Non-consecutive blocks permitted; both parents can take ShPL concurrently |
| Notice requirement | 15 weeks before EWC | 8 weeks advance written notice per block (up to 3 separate blocks) |
| Employment protection | Right to return: same job (OML); suitable alternative (post-AML) | Same return rights as maternity leave for equivalent duration |
Eligibility. Maternity leave requires one eligibility test — the mother must be an employee with 26 weeks of continuous service by the 15th week before her EWC. Shared Parental Leave requires two separate eligibility tests to be satisfied simultaneously. The complexity of the dual test is a key distinction in HR administration terms and a marker of distinction-level AC 2.1 answers.
Duration. Maternity leave totals 52 weeks. Shared Parental Leave offers up to 50 weeks, because the 2 weeks of compulsory maternity leave that open every maternity leave period cannot be shared. Both parents draw from the same 50-week pool, so concurrent use depletes the pot faster.
Pay. SMP pays 90% of average weekly earnings for the first 6 weeks, with no upper cap, then £184.03/week for weeks 7 to 39. ShPP pays £184.03/week from week 1 throughout the entitlement period. This financial difference is the single most important distinction for an AC 2.1 answer at distinction level.
Flexibility. Maternity leave is taken as a continuous block. ShPL can be taken in separate, non-consecutive blocks, and both parents can take ShPL at the same time — a feature unavailable under the maternity leave regime.
Notice Requirements — A Key Procedural Difference
Notice requirements differ substantially between the two leave types and carry real HR administration consequences. Maternity leave requires a single notification: the employee must inform her employer of her intention to take maternity leave by the 15th week before the EWC, specifying the intended start date. This is a one-time administrative step.
Shared Parental Leave generates up to three separate 8-week notice cycles. Under the Shared Parental Leave Regulations 2014, each block of ShPL requires at least 8 weeks’ advance written notice specifying the start date, end date, and type of leave. The employer has 2 weeks to respond. If the employee requests a discontinuous pattern — for example, alternating between leave and work across multiple weeks — the employer may agree, negotiate an alternative, or refuse. If the employer refuses, the employee may withdraw the notice or take the leave as a continuous block instead.
Where an employee uses all three permitted notice periods for non-consecutive blocks, the employer processes three separate notice and confirmation cycles. That administrative burden per leave episode is considerably higher than the single maternity leave notification requirement.
HR Compliance Implications of Maternity Leave and Shared Parental Leave
For HR practitioners, the differences between maternity leave and ShPL translate into distinct compliance obligations, payroll calculations, and policy design decisions.
Enhanced pay policies carry equality law risk. If an employer enhances SMP beyond the statutory rate — for example, paying full salary for the first 26 weeks — equality law under the Equality Act 2010 s.19 requires the employer to offer an equivalent enhancement to ShPP. A policy that enhances SMP but pays only the statutory flat rate for ShPP may constitute indirect sex discrimination against male partners, because it places a provision, criterion, or practice on the method of accessing enhanced pay that puts men at a particular disadvantage. The legal position is contested — the EAT considered related issues in Capita Hartshead Ltd v Duckworth [2016] — but ACAS recommends that employers who enhance SMP review their ShPP policy to ensure equivalence.
KIT days and SPLIT days differ in volume. Maternity leave permits up to 10 Keeping In Touch (KIT) days during the leave period. ShPL permits up to 20 Shared Parental Leave In Touch (SPLIT) days. Both types of day must be agreed between employer and employee. Neither type ends the leave period, and neither generates an additional week of entitlement.
Record-keeping obligations are greater for ShPL. Each block booking notice, employer confirmation letter, eligibility declaration, and SPLIT day agreement must be retained. For an employee who exercises all three block booking notices across two parents, the documentation per leave episode can exceed six formal exchange cycles.
Employment protection applies equally to both leave types under the ERA 1996. The right to return to the same job applies where the total leave period (maternity or ShPL) does not exceed 26 weeks. Where the leave exceeds 26 weeks, the right is to return to the same job or, where that is not reasonably practicable, a suitable and appropriate alternative. Maternity leave carries an additional protection not present in ShPL: under Regulation 10 of the Maternity and Parental Leave etc. Regulations 1999, a woman on maternity leave who is placed at risk of redundancy must be offered a suitable alternative vacancy in preference to other at-risk employees. This priority protection does not automatically extend to employees on Shared Parental Leave, making it a further compliance distinction that HR practitioners must understand.
Understanding employment regulation aims CIPD provides the broader legislative rationale underpinning both of these leave regimes and situates them within the AC 1.1 framework for the 5OS01 module.
How Do These Leave Types Affect HR Administration in Practice?
The statutory differences between maternity leave and Shared Parental Leave translate into distinct administrative processes, payroll calculation frameworks, and policy design requirements for HR teams. An employer who runs enhanced pay policies, manages concurrent leave requests, or handles block booking cancellations must maintain procedures for each leave type separately rather than applying a single parental leave process to both. The supplementary content below covers the model AC 2.1 answer structure and links to related pages within the 5OS01 specialist employment law cluster.
For a full worked example of how to present the AC 2.1 answer in a CIPD assignment submission context, the CIPD 5OS01 assignment example page sets out the complete module structure alongside distinction-level model answers for each AC.
Model Answer Structure for CIPD 5OS01 AC 2.1
A CIPD 5OS01 AC 2.1 answer has a defined structure at each performance level. The key structural requirement is that the answer explains differences — it does not simply describe each leave type in isolation. A pass-level answer identifies that maternity leave and ShPL are different types of leave and states some of the main distinctions. A distinction-level answer compares the two leave types on multiple specific dimensions, anchors each comparison to the governing regulation, names the specific statutory values, and addresses the financial inequality between SMP and ShPP along with its equality law implications for HR practice.
The comparison table format — covering legislation, eligibility, duration, pay, flexibility, and notice requirements — is a recognised structure for AC 2.1 answers because it demonstrates systematic analytical coverage across all relevant dimensions. Simply writing paragraphs about each leave type without directly comparing them does not satisfy the “explain the differences” requirement of the AC. The table format also supports the HR advisory framing of the typical scenario: an HR practitioner advising on the two regimes needs a clear comparative framework, not a sequential description.
The CIPD 5OS01 assignment example page contains the full worked assignment for the 5OS01 unit, including the AC 2.1 model answer at distinction level with Harvard references to the governing regulations.
What a Distinction-Level AC 2.1 Answer Includes
A distinction-level AC 2.1 answer goes beyond listing differences. It references both governing regulations by name — the Maternity and Paternity Leave Regulations 1999 and the Shared Parental Leave Regulations 2014 — and names specific statutory values for each dimension: £184.03/week (2024/25) for both the SMP flat rate and the ShPP rate; 90% of AWE with no cap for SMP weeks 1 to 6; 26 weeks as the eligibility service threshold; 50 weeks available for ShPL; and 8 weeks advance notice per ShPL block. A distinction-level answer also addresses the financial inequality between SMP and ShPP in the early weeks and notes the HR compliance implication of enhanced pay policies under the Equality Act 2010 s.19. A pass-level answer identifies the differences in general terms without statutory values.

Frequently Asked Questions — Maternity Leave vs Shared Parental Leave
Can both parents take maternity leave and shared parental leave at the same time?
Maternity leave cannot be taken simultaneously by two parents. It is a right exclusive to the mother (or primary adopter in adoption cases). Shared Parental Leave, by contrast, can be taken concurrently — both parents can be on ShPL at the same time provided each meets their own eligibility criteria and each submits a valid 8-week notice to their respective employers. Concurrent ShPL use depletes the shared 50-week pot faster: two parents taking ShPL simultaneously for 4 weeks consume 8 weeks from the shared entitlement.
Is Statutory Shared Parental Pay the same amount as Statutory Maternity Pay?
No. Both ShPP and SMP pay £184.03/week (2024/25) at the flat rate, but SMP includes an enhanced period for the first 6 weeks at 90% of average weekly earnings with no upper limit. ShPP pays the flat rate from week 1 with no enhanced period. For an employee earning £40,000 per year, SMP in weeks 1 to 6 is approximately £692/week, while ShPP from week 1 is £184.03/week. SMP is therefore worth significantly more than ShPP in the early leave period, which is the primary financial disincentive for partners taking ShPL.
What notice must an employee give before taking Shared Parental Leave?
Under the Shared Parental Leave Regulations 2014, an employee must give their employer at least 8 weeks’ advance written notice before each block of Shared Parental Leave begins. Up to 3 separate notice periods are permitted across the entire ShPL entitlement. Each notice must specify the start date, end date, and whether the leave includes ShPP. The employer has 2 weeks to respond to each notice. By comparison, maternity leave requires a single notification at least 15 weeks before the Expected Week of Childbirth, with no further notice cycles. The administrative burden per leave episode is substantially higher for ShPL.
Does Shared Parental Leave give the same employment protections as maternity leave?
In substantive terms, yes — with one significant exception. Both maternity leave and Shared Parental Leave carry the right to return to the same job where the leave period is 26 weeks or fewer, or to a suitable and appropriate alternative where the leave exceeds 26 weeks. Both leave types protect against dismissal or detriment connected to taking leave under the Employment Rights Act 1996 and the Shared Parental Leave Regulations 2014. However, maternity leave carries an additional protection under Regulation 10 of the Maternity and Parental Leave etc. Regulations 1999: a woman on maternity leave who is at risk of redundancy must be offered a suitable alternative vacancy ahead of other at-risk employees. This priority protection does not automatically extend to employees on Shared Parental Leave, representing a substantive employment protection distinction between the two regimes.
