Built for how you actually teach

Author once, differentiate for every learner, grade with an audit trail under every mark — and start each morning knowing exactly which student needs you today.

Author once, teach all year

Build the course the way you'd teach it — lessons, videos, quizzes, assignments — and schedule when each piece appears, so the term runs itself.

9 activity kinds in one authoring surface — video, reading, quiz, assignment and more
Question banks with randomization — write once, draw fresh papers per attempt
Rubric builder reused across assignments, with outcomes attached
Release dates and access rules — content appears on your schedule, not by hand
Class announcements composed once, landing on every student's course home
Per-lesson duration estimates so workload is visible before you assign it

Teacher course workspace showing published course state, module and activity counts and the reusable rubric library — Course builder — publish state, modules and activities at a glance, with a reusable rubric library. Captured from the live demo school.

Differentiate without spreadsheets

Pick a trigger quiz, set the score bands, choose the destinations — Zelarium routes each learner to remediation, core or enrichment automatically, and always tells them why something is locked.

Differentiated assignments: one trigger, up to three score-banded paths — validated so bands never overlap
Release rules on score, completion, mastery, date, group, attempts, level or badge
Per-student and per-group date overrides — accommodations without side lists
Groups and cohorts for group-scoped content and discussions
Every gate explains itself — students see a human-readable reason, not a mystery lock

Release rules panel with the differentiate-an-activity composer showing a needs-support score band — Release rules — the “Differentiate an activity” composer routes learners by score band. Captured from the live demo school.

Grading that holds up

A grading queue that clears fast, and a ledger under every mark — so when a parent asks "why did this change?", the answer is one click away.

Grader queue per assignment, with rubric scoring and feedback threads
Resubmission workflows with due-date and late status handled for you
Grade visibility controls — students see marks when you release them
Append-only grade history — who changed what, from what, to what, why, when
Manual-grading flags — essay items inside auto-graded quizzes surface themselves
Completion overrides and deadline extensions recorded as governed actions

Gradebook grid with released and hidden marks, weighted totals and a review-release button — Gradebook — marks stay hidden until deliberately released; every change lands in the grade history. Captured from the live demo school.

Quiz psychometrics: which questions were too hard, which distractors fooled everyone — honest blanks under low samples
Completion grids and score distributions — the whole class, one screen

Quick awards — recognise effort on the spot, with your note attached

Class insights at-risk queue showing three learners with stated reasons and intervention action buttons — Class Insights — an at-risk queue where every flag names its reason, with intervention actions. Captured from the live demo school.
