Model description

Switch-on is a targeted-indicated intervention for children aged 7 to 16 years who are working below age expectations for reading and writing. These include children who have not met the expected level in English at a Key Stage assessment. Children may have Special Educational Needs, or have English as an Additional Language. Switch-on may also be run in Special Schools.

Switch-on is delivered by a teaching assistant or other trained practitioner (such as a teacher, librarian, or SENCO) to individuals. The practitioner delivers one-to-one sessions approximately daily for 20 minutes over 10 to 12 weeks (one school term).

There are currently two different versions of Switch-on: Switch-on Reading, and Switch-on Writing. Switch-on Reading is underpinned by robust evidence.

In Switch-on Reading, materials are selected based on pre-test scores and prior attainment in the first session; if a mismatch with the pupil’s reading ability becomes apparent, this can be adjusted in the following session. Over the course of the intervention, pupils read both fiction and non-fiction books which include visual images. Each session includes: reading a familiar book, discussing the textual and visual content of a book, and introducing and reading a new book. Pupils practise reading comprehension through the discussion, and the practitioner provides feedback and tips on reading strategies. The practitioner also keeps a record sheet with an inventory of reading errors made by the pupil each week; there is a standardised way of completing the record sheet, which forms an important part of the intervention.

A historic, hybrid version of the intervention focused on both reading and writing, with reading sessions alternating with writing sessions. In the writing sessions, pupils read one book, and wrote out a sentence from that book with support.

The aim of the intervention is to achieve functional literacy for pupils, and close the reading gap between the most disadvantaged children and their peers. It does this through teaching pupils to be active independent readers and writers.

Age of child

7 to 16 years

Target population

Children with reading and writing below expected age level

Why?

Science-based assumption

Lack of functional literacy is a barrier to academic achievement and positive life chances.

Science-based assumption

Lack of functional literacy and low engagement in reading in childhood is a barrier to accessing the curriculum and achieving at school.

Who?

Science-based assumption

Pupils who are reading at below the age-expected level.

How?

Intervention

Trained teaching assistants have daily sessions with pupils to encourage active independent reading and writing, through reading practice, introduction of vocabulary, and discussion of comprehension questions.

What?

Short-term

Improved pupil engagement with reading

Improved pupil reading (phonics)

Improved pupil reading comprehension

Improved pupil writing.

Medium-term

Improved access to the curriculum

Increased academic achievement.

Long-term

Increased academic achievement

Improved life chances in adulthood.

Who is eligible?

Children aged 7 to 16 years who are working below age expectations for reading and writing.

How is it delivered?

Switch-on is delivered in 40 sessions of 20 minutes’ duration each, approximately daily over 1o to 12 weeks, by a trained educational practitioner to individual pupils at school.

What happens during the intervention?

In Switch-on Reading, the practitioner, usually a Teaching Assistant, meets almost daily with the pupil to read and discuss books together, including re-reading familiar books and reading new books. They discuss the text, vocabulary, and phonics, and the practitioner gives reading strategy tips.

The aim is to improve children’s independent reading and literacy skills, as well as writing.

Who can deliver it?

The practitioner who delivers this intervention is a Teaching Assistant, Librarian, Teacher, or SENCO.

What are the training requirements?

The practitioners have 2 days of intervention training. Booster training of practitioners is not required.

How are the practitioners supervised?

It is recommended that practitioners are supervised by one intervention developer supervisor, with seven hours of intervention training.

What are the systems for maintaining fidelity?

Intervention fidelity is maintained through the following processes:

  • Training manual
  • Video or DVD training
  • Fidelity monitoring.

Is there a licensing requirement?

Switch-on’s most rigorous evidence comes from an RCT which was conducted in the UK, consistent with Foundations’ Level 3 evidence strength threshold.

This study evaluated a version of Switch-on Reading, and identified statistically significant improvements in reading.

There is also evidence from an RCT conducted in the UK, consistent with Foundations’ Level 2+ evidence strength threshold, which identified statistically significant improvements in writing, and from a rigorous RCT conducted in the UK which did not observe any positive impact of the intervention. Both of these studies evaluated a version of Switch-on which focused on both reading and writing.

Switch-on therefore receives a rating of Level 3+* overall: its evidence base includes mixed findings. This includes rigorously conducted studies suggesting positive impact alongside studies, which, on balance, indicate no effect or negative impact.
