Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? FAST did not work significantly better or worse for any subgroups of students or in schools with particular characteristics. → Bos 2018

In the 60-school cluster RCT (1,396 students), subgroup and school-characteristic analyses found no differential impact: "did not find that FAST worked significantly better or worse for any subgroups of students or in schools with particular characteristics."
"We also did not find that FAST worked significantly better or worse for any subgroups of students or in schools with particular characteristics."
