Student Scores Aggregated into Cache Tables
We want to perform stats on collections of individual student scoresets. These scoresets are collected over:
- class (teacher) - NULL teacher needs to be considered/included.
- school (collection of teachers)
- district (collection of schools)
- state (all districts)
This leads naturally to:
- admin_teacher_score_cache
- admin_school_score_cache
- admin_district_score_cache
- admin_state_score_cache
Entities
