Subclaims¶

q3 i? Earlier initial exposure to City Connects is associated with more beneficial treatment effects (OR = 1.186, p = .000), with effects remaining statistically significant through initial exposure in grade 3 but no longer significant for grades 4 or 5. → Walsh 2015

q3 · i? · causal · r2

The same quasi-experimental event history analysis incorporated an initial City Connects grade covariate at the student level, assuming treatment effect linearity across exposure grades. The study reports "more beneficial treatment effects (OR = 1.186, p = .000)" for earlier exposure, with effects no longer statistically different from zero when initial exposure occurs in grades 4 or 5.

"Additionally, we find that earlier initial exposure to City Connects is associated with more beneficial treatment effects (OR = 1.186, p = .000). Although treatment effects decrease as initial exposure grade increases, beneficial treatment effects remain positive and statistically significant through initial exposure in grade 3."

Related Claims¶

• Elementary school City Connects exposure is associated with approximately half the odds of high school dropout relative to no exposure — a narrower finding that bears on this claim
• The main dropout-contagion findings remained essentially unchanged across five robustness checks including unmatched samples, IPTW, and conditional regression — related
• Each year of City Connects dosage predicts small significant increases in grade 5 math, reading, writing, and effort scores — related
