q2 i? Sensitivity tests estimate per-participant costs of $17.85 (2 years, no local coach), $25.86 (no warm-up), and $8.85 (no warm-up, no local coach), versus $46.23 in the primary scenario. → Feng 2024

q2 · i? · causal · r2

Sensitivity analysis (Table 2) varying length of professional development, availability of a local coach, and necessity of a warm-up year; the developer expected satisfactory implementation might be achieved with only one year of professional development.

"The primary costs in Table 1 reflect that costs during both years of implementation were the essential ingredients for producing the observed differences during the study in math outcomes between students in the classrooms of intervention teachers and the students in the classrooms of comparison teachers."
