AR is a digital reading management and monitoring programme that aims to encourage independent reading.
Looking at the KS2 Sats reading scores of pupils who had started with the programme in Year 5, EEF found that they made no additional progress in reading, on average, compared with pupils in schools not using the approach.

There is also some indication that the same applies to children eligible for free school meals, although these results have "high statistical uncertainty", the EEF reports.
Most of the schools that did not use the programme, which served as a control group, had similar amounts of dedicated reading time and some used other evidence-based schemes and reading interventions, the report notes.
The evaluation also found that the programme was "very well received" by the vast majority of teachers, teaching assistants, and librarians who perceived positive impacts on pupil reading ability, reading stamina, and attitudes.
Another set of data analysing the long-term impact of AR KS2 reading scores for pupils who did the programme in Years 4 and 5 found similar results as pupils made no additional progress compared with those in control schools.
As for FSM pupils, it found that, on average, they made one month of additional progress in reading, but the result had again a high level of statistical uncertainty.
