q2 · i? · qualitative · r1

The interview reports the dissemination trajectory as a retrospective account: growth from three schools to 75 schools by 1998–99, with the later figures of about 3000 schools and over half a million students per year also stated in the interview. No effect size applies, so impact is null.

"From the three schools involved in this study in the 1993 –94 school year, we reached 75 schools in the 1998–99 school year (Corbett et al. 2001)."
