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.
q2 i? Analyses of four perception studies (two school-level, two student-level) found no statistically significant relationship between SBLE and perceptions of school. → Fisher 2022
q2 i? Among two school-level studies, SBLE was associated with improved perceptions of safety, but the two student-level studies found no statistically significant relationship. → Fisher 2022 (2)

Fisher 2022¶
Fisher, B., & Petrosino, A. (2022). What a systematic review of 32 evaluations says about the impact of school-based law enforcement. WestEd. https://eric.ed.gov/?id=ED621156
q2 · i? · quant-synthesis · r1
Meta-analytic synthesis of two school-level and two student-level studies of SBLE and perceptions of school. The review reports "no statistically significant rela - tionship between SBLE and perceptions of school"; no effect size is printed.
"For both kinds of studies, analyses found that there was no statistically significant rela - tionship between SBLE and perceptions of school."

q2 · i? · quant-synthesis · r2
Perceived-safety analyses from the same review: an association with improved safety perceptions in two school-level studies, but no statistically significant relationship in the two student-level studies. The brief prints no effect size.
"Among the two school-level studies, SBLE was associated with improved perceptions of safety. However, the two student-level studies found no statistically significant relationship."
Discussion¶
Learner Variables¶
- Safety — outcome: instruction changes it
