TeachEdge vs DeepMark

A teacher-controlled assessment workflow for UK secondary: set a task, students submit, draft marks are generated, the teacher reviews and releases. DeepMark marks GCSE and A-Level across AQA, Edexcel, OCR and WJEC, and is built for a department rather than a teacher working alone.

We make one of these two, so read us accordingly. Everything we say about TeachEdge below was read from their own public pages and is dated.

Choose TeachEdge if

One teacher’s own assessment loop, end to end, across 23 subjects — at a price you can read without booking a call.

Choose DeepMark if

The pile is bigger than one person. Split a mock across the department, see who has done what, and keep the papers and schemes somewhere they survive a teacher leaving.

The real difference

TeachEdge models how a department works, but each teacher gets their own copy of that workflow — and a shared workflow is not a shared workspace. In DeepMark the papers, the mark schemes and the marked scripts are one library the department holds, so a mock can be split across the team and finished to a date rather than whenever the last person gets to it.

Practically, that means a mock pile splits across whoever is free and you can see who has done what. It fits the way your department already marks — down a whole script, or one question at a time across the pile the way an examiner does. Marks that disagree get flagged instead of found at results day. And the papers, the schemes and the marked work stay in one shared drive rather than on somebody’s laptop, which matters the term a teacher leaves. Two people can be inside the same script at once when you need it; most weeks you will not.

None of it depends on AI. The manual studio marks with no AI in the loop at all, which matters if your department has not settled that argument. And the point of the whole thing is the question that comes after the marking: which questions cost the cohort marks, which class, which assessment objective. That is where this is going, and the list below says plainly what is live today and what is still coming.

Our read on TeachEdge

The most complete single-teacher assessment loop here — set, submit, draft, review, release — built by a practising teacher and priced openly from £5 a month. It is shaped like a department's workflow, but each teacher runs their own copy of it: no shared library, no moderation layer, nothing that advertises more than one person on a paper. Strongest children's-data position of any tool covered. The gaps are evidential rather than functional: no accuracy figure of any kind, and no named AI sub-processor.

What DeepMark does

Ticks are live today. Anything still coming says so.

Core marking

Get a class set in, and get it back marked against the board's own mark scheme — in whichever way your department already marks.

  • Bulk PDF upload, a whole class set at once
  • Snap photos from a phone
  • Handwriting extracted to textIncluding messy writing and crossings out.
  • First-pass marking against your mark schemeOptional. The manual studio below does the same job with no AI involved.
  • Manual marking studio with AO taggingMark by hand, digitally, with no AI in the loop at all.
  • Mark one question at a time down the pile, like an examinerOn the roadmapThe e-marker way of working, for departments that already mark that way. Delegating a question across a cohort is live today; working down the pile question-first is what we are building next.
  • Teacher reviews, edits or challenges every mark
  • Adjustable grade boundaries
  • AQA, Edexcel, OCR and WJEC mark schemes
  • GCSE and A-Level

Collaboration and delegation

The part no other tool in this directory advertises: more than one teacher, in the same marking.

  • Two teachers inside the same script at onceReal-time collaborative editing, with live cursors.
  • Share a script with a colleague for a second look
  • Delegate by question across a whole cohortOne question per teacher, everyone marking at the same time — the way an exam board does it.
  • Parallel marking, so a year group finishes together
  • Shared department drive
  • Teams, with a shared workspace per department
  • Ask DeepMark why a mark was given, mid-reviewAvailable when AI marking is switched on.

Moderation and quality

Standardisation that covers every script, not the sample you had time to check.

  • Moderation dashboard
  • Full audit trail on every mark
  • Automatic flagging where two markers disagreeOn the roadmap
  • Automatic flagging of drift within one marker's batchOn the roadmap
  • Safeguarding content flaggingOn the roadmap

Insights and analytics

What the marking is actually evidence of — question by question, skill by skill, while there is still time to act on it.

  • Class mapped question by questionOn the roadmap
  • Department and cohort roll-upOn the roadmap
  • Assessment objective tracking over timeOn the roadmap
  • Common misconceptions surfaced across a cohortOn the roadmap
  • Writing quality, beyond a percentageOn the roadmap

Getting it back to students

Marking that ends with the student, not with the spreadsheet.

  • Annotated scripts as PDF
  • What went well and even better if, per student
  • Individual student reports
  • Department-ready spreadsheets
  • Student-facing handbackOn the roadmapStudents see their own marked script and feedback directly, rather than a printout.
  • Feedback lessons shaped by the marking dataOn the roadmap

Compliance and security

The questions a data protection lead asks before anything else.

  • Student data stored in the UK
  • AI processing in the EU, under UK adequacy
  • Never used to train AI models
  • Never used for advertising
  • Data minimisation by default
