Context + education + attendance joint model (student-weighted)
Metric: Percent Proficient
Attendance field: Attendance_Percent_Regular_Attenders
Generated: 2026-02-21 17:50:42

Context specs included:
- Income: ACS_Median_Household_Income
- Poverty: Students Experiencing Poverty

Note on betas: standardized regression coefficients from 'Percent Proficient ~ context + education + attendance'. Variables are z-scored using student weights. A beta indicates the change (in SD units) in the metric for a 1-SD increase in the predictor, holding the others constant.

Filters: Student Group = Total Population; All Grades dropped if grade-specific rows exist.
