Reach by year group (% of pupils in each year using the product)
STAR has the broadest reach — 86–100 % of Y3–Y9 sit the diagnostic. MyOn is the Primary e-library (fades from Y7). AR Reading Practice surges in Y7–Y8 (89–91 %) where Secondary English uses it for accountability quizzing.
Next year (Y3–Y11) projection admissions numbers + 5/yr buffer · reach % held from this year
Y3–11 roster: 446 admissions + 45 buffer = 491. Down from 504 this year (−13 students).
Projected users: MyOn 231 (was 235), STAR 387 (was 401), AR 280 (was 298). Notable cohort dip in Y4 (44) and Y7 (43) where this year was bigger.
Recommended starting point: Scenario B (£8,928 — saves £1,112). Same products, same year groups, just right-sized to next year's admissions-based projection with 10 % headroom. From there, decide with the leads whether Secondary MyOn (saves another £316) or KS4 AR (saves another £167) is worth the trim.
STAR — test windows (student-test-days by month)
Three clean test windows: Sep, Dec, Feb — matches a termly diagnostic schedule.
STAR — median tests / student by year
Most year groups average 3 tests/year. Y3 over-tests (median 5) — confirm with primary leads.
