For headteachers: time back for teachers, every mark still theirs

Piarrel takes the routine part of marking off your teachers and keeps every decision with them.

What it changes for a school

  • Time: at the trial school, teacher time per class set was 26 minutes in Piarrel, against about 1 hour 45 minutes on paper.
  • Illustratively: for a 40-teacher school, that is about 1,600 hours a year (40 teachers × 5 classes × 6 tests, about 80 minutes saved per test).
  • Printing: for the same school, about €10,800 a year in printing avoided. Illustrative: 18 pupils × 10 pages × €0.05 a test, with the page cost measured at the trial school.
  • Control: a teacher approves every mark before a pupil sees it, and every decision is kept in an audit trail.
The marking queue: a pupil's answer beside the mark-scheme point, with Piarrel's proposed mark, its reasoning and its confidence.
Every mark is proposed for a teacher to approve or change, with its reasoning.

One view across the school

Heads of department see their department's papers and released results by teacher, class and subject. Headteachers see the same view across the whole school.

The headteacher's view across the whole school: pupils assessed, assessments run and the school average.
The headteacher's view: the same analytics, across the whole school.
