Plain English Summary

Background and study aims
Peer-Assisted Learning Strategies for Reading UK (PALS-UK) is a form of class-level interventions in schools with the aim of improving children’s reading comprehension and fluency. It pairs pupils with stronger and weaker skills, who read to each other and correct mistakes in the reading of their assigned partner. PALS-UK have been widely implemented and studied in the US, but high quality, rigorous evidence is lacking. It is a strong candidate for evaluation as it provides structure for within-class peer interactions, which is supported by the literature and makes scale-up more feasible.

Who can participate?
All Year 5 pupils at participating state schools

What does the study involve?
All Year 5 teachers will receive the PALS-UK manual and resources needed to deliver the intervention. In addition, all Year 5 teachers will receive initial training (1 day), top-up training (half-day) and various other opportunities throughout the year to support them in the implementation of PALS-UK. Schools with two or more Year 5 classes will be asked to implement PALS-UK in all of them. However, only children in one randomly selected class will undertake outcome testing at the beginning and end of the project. In schools with one Year 5 class, one additional teacher within the school should attend the PALS-UK training to act as a peer observer as part of the intervention. Intervention schools will receive a selection of books to help support the delivery of PALS-UK.

What are the possible benefits and risks of participating?
PALS-UK can benefit schools in multiple ways, such as raising the profile of language in primary schools and providing schools with professional support for teaching and learning. Furthermore, studies have found positive effects of peer tutoring in relation to reading skills, such as accuracy, comprehension and fluency. Schools in the control group will receive small monetary compensation and can choose to implement PALS-UK once the study is completed. Intervention schools will be charged a fee of £200 for taking part in the PALS-UK intervention. This fee will cover teacher training and resources (including books and the intervention manual). There is minimal risk in this evaluation which largely consists of the completion of surveys. There is a small risk that confidential information is released to the public. Only RAND and Coventry University will have access to any of the information that is collected. RAND will monitor any concerns teachers may have through surveys and will report anonymous and aggregated results to the implementation team and schools.

Where is the study run from?
The study is run from:
1. RAND Europe (Independent evaluator)
2. Coventry University (Intervention delivery team)

When is study starting and how long is it expected to run for?
December 2018 to December 2020

Who is funding the study?
Education Endowment Foundation (UK)

Study hypothesis

Hypothesis 1: Year 5 pupils in randomly allocated primary schools participating in PALS-UK (intervention schools) will have higher levels of reading attainment than pupils in control schools within the couple of months following the end of PALS-UK implementation in Summer 2020 (Primary outcome)
Hypothesis 2: Year 5 pupils in randomly allocated primary schools participating in PALS-UK (intervention schools) will have higher self-efficacy in reading than pupils in the control schools by summer 2020 (Secondary outcome)
Hypothesis 3: Year 5 pupils in randomly allocated primary schools participating in PALS-UK (intervention schools) will have higher levels of reading fluency and oral skills than pupils in the control schools by summer 2020 (Secondary outcome)

Reading comprehensions and fluency in typically developing children in Year five


Peer Assisted Learning Strategies for Reading UK (PALS-UK) is a whole-class structured paired reading intervention that is designed to improve children’s reading fluency and reading comprehension skills. Pupils are paired and take it in turns to act as tutor and tutee in a set of structured activities. PALS sessions comprise of four activities: (i) partner reading, in which the tutor corrects the tutee’s reading errors using the PALS check-it procedure; (ii) re-tell, in which the tutee re-tells a story with prompts from the tutor; (iii) paragraph shrinking, in which both pupils summarise what they have read using ten or fewer words; and (iv) prediction relay, in which both pupils have to predict what will take place in the next half-page of a story after reading each half page. As an intervention, PALS-UK is quite intensive: each session lasts 30-35 minutes and takes place three times a week over a period of 20 weeks.

In this evaluation, PALS-UK will be delivered to children in Year 5 classes in approximately 80 schools in England. Approximately half of the schools will be in the Midlands and half will be in the North East England. Schools will be recruited by Coventry University but allocated to either the intervention or control group by RAND Europe. Region will be the main stratifying variable, as around half of the schools will be recruited from the Midlands and another half from the North East. In addition, the researchers plan to stratify on school size (single-entry versus multiple-entry school), as reported by the school.

Control group: Schools in the control group will teach “business as usual”, apart from that pupils will be asked to participate in outcome testing, which will be independently administered and invigilated in September 2019 and June 2020.
Intervention group: The implementation of PALS-UK will involve the following activities:
1. All Year 5 teachers in intervention schools will receive the PALS-UK manual and resources needed to deliver the intervention
2. Teachers from Year 5 classes will attend two training sessions: one full day session and one half day top-up session.
3. Children will undergo training for four weeks, which will be provided by their Year 5 teachers. This will focus on how to deliver the activities and how to work well in pairs
4. Children will work in pairs for 32 minutes, three times a week during the autumn, winter and spring terms of 2019/2020. This will continue for 14 weeks after the initial training. These sessions will be observed by teachers.

Intervention schools with two or multiple-entry Year 5 classes will deliver the intervention in all classes, but only one randomly selected Year 5 class will be tested. This will significantly reduce testing costs but will have only a small effect on the power of the study. The selected Year 5 class will be asked to complete a reading attainment test at the beginning (September, 2019) and the end of the programme (June 2020).

The outcome analysis will be on an intention-to-treat (ITT) basis. The analysis will include all randomized schools in the groups to which they were randomly assigned, regardless of the treatment they actually received, withdrawal post-randomisation, or deviations in programme implementation. This principle is key in ensuring non-biased programme effects. This approach compares outcome means for the treatment and comparison groups, and subjects are analysed according to their randomised group allocation. The ITT approach is inherently conservative as it captures the averaged effect of offering the intervention, regardless of whether or not the participants complied with assignment. The primary outcome is pupil-level PiRA test scores standardised with mean 0 and standard deviation 1. To estimate the impact estimate on the primary outcome we will use a two-level multilevel model to account for clustering of data.

Drug names

Primary outcome measure

Reading attainment will be measured using the Progress in Reading Assessment (PiRA) test at baseline and 9-months

Secondary outcome measures

At baseline and 9-months:
1. Oral fluency and language comprehension based on the Wechsler Individual Achievement Test–III (WIAT III) oral fluency and reading comprehension subscale
2. Reading self-efficacy. Self-efficacy refers to children’s beliefs in their capability to produce satisfactory attainment. The final measure is yet to be confirmed

Participant inclusion criteria

Schools will be recruited by the Delivery team (Coventry University), based on the following eligibility criteria:
1. Schools have never used PALS in the last three years
2. Schools have not taken part or will not take part in other trials for KS2 in the school year of 2019/2020
3. Schools should not have mixed age classes. There must be at least a one single-form entry Year 5 classroom in the school

All Year 5 teachers in schools taking part in the trial

There are no inclusion/exclusion criteria based on pupil characteristics as PALS-UK is a whole-class intervention. children with Special Educational Needs and Disabilities (SEND) will not be paired with other children but will implement PALS activities with a Teaching Assistant (TA).

Target number of participants

Schools: 89, Participants: 2,900

Participant exclusion criteria

To minimise burden on schools, pupils enrolled at the time of school recruitment in 2019 are included in the study, but pupils who join the schools at a later time will not be included in the evaluation as this would require additional information collected from schools. Parents can withdraw children at any time.
