IndigoBell I would treat the report with caution and not draw conclusions from it as to which intervention is most effective. As you have probably noticed the same intervention carried out by different authorities can have hugely different outcomes
AcceleRead in Devon had a reading gain of 16+ whereas in Jersey it only gave a gain of 8+ ...
Any programme is only as good as the staff delivering it!
both AcceleRead and Arrow are phonic programmes
from the report
Focusing on phonological skills for reading
Phonological skills, including spelling, were the focus of the largest number of studies. Among those
analysed here, the following mainly phonological schemes focused on reading:
Fourteen main schemes: ARROW, AcceleRead AcceleWrite, Direct Phonics, Lexia, Phono-Graphix?,
[PAT], Phonology with Reading, Read Write Inc. (including Fresh Start), SIDNEY, Sound Discovery,
Sounds~Write, Sound Training for Reading, THRASS and Toe by Toe;
We use LEXIA as our main intervention and find it effective when delivered by skilled staff.
I'm not a fan of AcceleRead - Direct Phonics - Read Write (in FS & KS1) THRASS or Toe to Toe and haven't had experience of using Arrow
