Year-over-year diff — see exactly what changed
HistorikDiff compares last school year with the next: which teachers got new subjects, who lost a class, where hours were adjusted. Grouped by teacher, year group and subject — with search and CSV.
New / Removed / Changed per row
Each allocation is tagged as new, removed or changed. Changes show the delta in hours (e.g. +2h/wk or -1 class).
KPI strip at the top
Total new / removed / changed allocations — so leadership sees the scope of the negotiation round at a glance.
Search + grouped view
Filter by teacher, subject or year group. Results are grouped so you see the full context — not just a row.
CSV export for unions & council
Export the diff as CSV — used as an annex to union negotiation or council governance meetings.
Only reads published sign-offs
HistorikDiff only compares allocations that have passed sign-off — half-finished drafts don't pollute the totals.
Also across multiple years
Pick 2024/25 against 2026/27 to see two-year change — relevant for council reporting.
In the classroom
Union representative
Verifies no teacher got a dramatically different load without consent — the history serves as the meeting annex.
Headteacher
Explains to council where the new hours came from and which initiatives drew resources.
Next year's planner
Learns from last year's decisions — where turbulence hit, where allocation stayed stable.
