You are accountable for marking consistency across your department, for cohort outcomes, and for the quality of every assessment that goes out under your subject’s name. You currently have no instrument that measures any of it.

Standardisation · 0580/42 · one script, six markers
The problem
Marking consistency and cohort outcomes are the two things a head of department answers for. Both are assumed to be under control, and neither is visible. Standardisation happens once a term, in a meeting, over a handful of scripts, and what comes out of it is a shared feeling rather than a measurement. Nobody leaves the room knowing which colleague is severe on method marks.
The data drop tells you a class got 61%. It cannot tell you that forty percent of the marks the year group lost went on three criteria, two of which you could reteach in a single lesson. So reteaching gets sprayed across a topic instead of aimed at a misconception, and the same marks go missing again in the summer.
None of this is a failure of professional judgement. It is the absence of an instrument. Six good teachers marking the same script to the same scheme will still produce a spread, because that is what unmeasured human marking does.
Who in my department is severe on method marks?
No current answer.
Which three criteria cost Year 11 the most marks?
No current answer.
Has every syllabus point been assessed this term?
No current answer.
Would two teachers give this script the same grade?
No current answer.
Six capabilities
Built for the person who signs off the department.
Send one script to the whole department. Everyone marks it blind. Phloem shows you the spread — who is generous, who is severe, and on exactly which criteria they diverge. That is the chart at the top of this page, and it is the thing your line manager assumes you already have.
Percentages tell you a class got 61%. They don't tell you that 40% of the marks lost across the year group went on three criteria. Phloem ranks the whole cohort's losses by marks forfeited, not by topic, so reteaching is aimed rather than sprayed.
Upload the department's scheme of work once. Every assessment built afterwards is mapped to a week and a set of syllabus points, so a teacher joining in January can see what has been assessed, what hasn't, and what is coming.
Someone is off at 7:40am. In under a minute you get a worksheet on last week's content, a fully worked answer sheet, and instructions plain enough for whoever is free period three — whether or not they have ever taught the subject.
The engine that marks a student's working criterion by criterion is the same one behind every set your teachers hand back. Method marks survive arithmetic slips. Follow-through is judged against the candidate's own earlier answer. Every mark is appealable, and the appeal goes to the teacher, not to us.
How do I introduce moles to a class that can't do ratio yet? What board diagram makes refraction land? Which misconception is behind half my class writing this? Ask it, and get an answer with the diagram drawn out, ready to copy onto the board — not a lesson plan template.
Scan to mark · in build
The workflow was designed around how marking actually happens in a department — on paper, in a rush, the evening before it is due back. Upload is live in beta and mark-back for Mathematics runs end-to-end for early departments; the rest of the pipeline is being finished ahead of your first series.
Photograph the pile of scripts, or upload PDFs from the department scanner. No special paper, no QR stickers, no barcodes to print beforehand.
Phloem reads the names and question numbers and assembles each candidate's script back together, including pages photographed out of order.
Every script is marked criterion by criterion against the same scheme — the identical engine across every class in the department.
Anything genuinely borderline is routed to the teacher for a spot-check rather than guessed at. You review the handful that need judgement, not all ninety-two.
Students don’t need an account. Mark the stack, publish grades, hand back.
A useful control surface
A head of department needs operational answers: what has been built, which classes have received it, and how much marking has made it back for review. The example below shows that shape without pretending it is live data.
Example department view
One glance at what has been set, reached a class, and come back for review.

Multiply the first figure by the number of teachers you line-manage. That is the budget you are actually spending on assessment, and almost none of it buys you consistency — because every one of those hours is spent alone.
What we can’t show you yet
Phloem for Departments is in build. We have no usage data, no case studies and no customer logos, and we are not going to borrow anyone else’s. Signing up early is the bridge: run it free through your first exam series, and the numbers you get out are your department’s own.
Safety & integrity
Four limits we designed in, rather than four questions we would rather you did not ask.
Every mark is appealable, and the appeal lands with the teacher. Phloem proposes a mark and the reasoning behind it. A teacher who disagrees changes it in one tap, and the change is what the student sees. Nobody's professional judgement is being automated away.
Students get the criterion they dropped, an explanation of the mistake, and another question on it. It teaches through marking — not through open-ended chat. The explanation is tied to the mark scheme, not generated on demand, so what they learn is what the examiner was looking for.
Export everything, delete everything, whenever you want. No minimum term, and no data held back to make leaving expensive. If Phloem is worth having it should be worth renewing, not hard to escape. Ask for a data processing agreement and you get one before anything is uploaded.
Phloem is not affiliated with or endorsed by Cambridge Assessment International Education. It marks against published specification criteria. Every question in it was written for Phloem — no past paper and no published mark scheme has been reproduced.
Pricing
Solo is per teacher. Department and Institution are per subject and per school. Purchase orders and invoices accepted, on your finance office's terms rather than a card form. The figures below are the planned list prices — they only apply once your first series has been marked.
Free through your first exam series. You set the price after.
Departments that sign up now pay nothing until their first series is marked, tell us what it was worth, and get the subject they teach built first. No contract, no procurement cycle to start, and the list prices below are what a department joining after launch would pay.
