Learning and Teaching Toolkit

Extending school time

Low impact for moderate cost, based on moderate evidence.

What is it?

This summary focuses on extending core teaching and learning time in schools and the use of targeted before and after school programmes. Other approaches to increasing learning time are included in other sections of the Toolkit, such as Homework, Early years intervention and Summer schools.

The research focuses on three main approaches to extending teaching and learning time in schools:

  • extending the length of the school year;
  • extending the length of the school day; and
  • providing additional time for targeted groups of learners, particularly disadvantaged or low-attaining learners, either before or after school. 

How effective is it?

The evidence indicates that, on average, learners make two additional months' progress per year from extended school time and in particular through the targeted use of before and after school programmes. There is some evidence that disadvantaged learners benefit more, making closer to three months’ additional progress. There are also often wider benefits for low-income students, such as increased attendance at school, improved behaviour, and better relationships with peers.

In addition to providing academic support, some school programmes aim to provide stimulating environments and activities or develop additional personal and social skills. These programmes are more likely to have an impact on attainment than those that are solely academic in focus. However, it is not clear whether this is due to the additional activities or to improved attendance and better engagement.

The research also indicates that attracting and retaining learners in before and after school programmes is harder at secondary level than at primary level. To be successful, any increases in school time should be supported by both parents and staff, and extreme increases (for example more than nine hours of schooling per day in total) do not appear to be additionally beneficial.

How secure is the evidence?

The evidence is moderately secure. Decisions to lengthen the school year or school day are often one component of wider approaches to school reform. This makes attributing any learning gains to the additional time itself difficult. Gains are not consistent across studies, indicating that additional time alone is not enough — it must be used effectively. Discrete or targeted programmes are more likely to have been evaluated robustly than other ways of extending learning time, and even here there is substantial variation in impact.

Most of the evaluations of extending school time come from the USA. The reviews all note the need for more rigorous evaluations with outcome measures that demonstrate direct impact on learning. Evidence from the UK is relatively scarce.

What are the costs?

The main cost is additional teacher time. Costs are estimated as moderate.

What should I consider?

Planning to get the most from the extra time is important. It should meet learners’ needs and build on their capabilities.

After school programmes with a clear structure, a strong link to the curriculum, and well-qualified and well-trained staff are more clearly linked to academic benefits than other types of extended hours provision.

After school programmes could give the opportunity to carry out some more intensive tuition (see entries for one to one or small group tuition).

Enrichment activities without a specific focus on learning can have an impact on attainment, but the link is not well-established and the impact of different interventions can vary a great deal (see entries for Sports or Arts participation).

Have you explored how the quality of teaching and learning during school time can be improved? It might be cheaper and more efficient to try introducing more evidence-based programmes or practices into the existing school day first.

Challenge questions to support collaborative self-evaluation

  • How effectively do we consult and plan with learners to best meet their needs?
  • How effectively are learners using a range of resources within and beyond the school day, including outdoor spaces and community resources, to support their learning and close the poverty-related attainment gap?
  • To what extent are we ensuring sustainability of benefits secured by specific monies, for example, PEF?
