What is on-screen marking?
On-screen marking (OSM) means evaluating exam answer scripts on a computer screen instead of on paper. The scripts are digitized, the candidate’s identity is hidden, and evaluators mark the digital copy. The system records each mark, adds up the totals and logs who marked what and when.
You’ll also hear it called OSM evaluation, digital evaluation, on screen evaluation or e marking. The terms vary by country and board, but they describe the same thing: answer sheet evaluation moving from a stack of answer books in a valuation room to a controlled digital workflow.
An on-screen marking system does more than display scanned pages. It runs the workflow around the marks, including allocation, anonymity, valuation passes, checks, approvals and the record that links each mark to a result.
How is on-screen marking done?
This is how answer script evaluation runs in Proctorly Examination, from the answer book to the published result.
1. Digitize scripts with chain of custody
Each answer script is digitized and keeps a chain of custody, so you can show where it has been between the hall and the evaluator. Because hall operations track answer books, every script that was issued, written and collected is accounted for before marking starts. The scanning setup and equipment for your centers are agreed during onboarding.
2. Hide candidate identity
Marking is anonymous. Evaluators see the script without the candidate’s name, so the mark reflects the answer rather than the person.
3. Mark on screen
Evaluators mark the digital script. A face check runs on each evaluator while they mark, so the institution knows the person assigned to a script is the one who marked it.
4. Run multiple valuation passes
Proctorly supports multi-pass valuation with variance rules. A script can be valued more than once, and the variance rules decide when marks from different passes are far enough apart to need another look. That’s how institutions keep evaluation consistent across a large panel of evaluators.
5. Approve and publish results
Marks go into results on the same record, with no export or re-entry. Grading rules, SGPA and CGPA, the exception center and committee approval all apply before controlled publication.
6. Handle revaluation
Revaluation requests come in with payment and are tracked to a new result. The original marks, the revaluation and the revised result all stay on record, so the trail is complete if the student appeals again.
What the Proctorly on-screen marking system includes
Everything below is part of Proctorly Examination.
- Script digitization with chain of custody. Every script is accounted for from collection to marking.
- Anonymous marking. Evaluators can’t see candidate identity.
- Multi-pass valuation with variance rules. Scripts get more than one valuation where your rules require it, and variance rules trigger a further look.
- AI mark suggestions. A suggested mark appears beside the answer, and the evaluator has the final say.
- Evaluator face check. The evaluator’s face is checked while they mark.
- Results on the same record. Grading rules, SGPA and CGPA, exception center, committee approval and controlled publication.
- Revaluation. Requests come with payment and are tracked to a new result.
- Tamper-evident audit trail. Every view, decision and change is logged.
Questions drawn from the outcome-mapped bank keep their mapping to course outcomes and Bloom’s levels, so marks feed accreditation analytics with no extra work. Our question bank software page covers the bank side.
AI mark suggestions, with the evaluator in charge
AI can speed up marking by offering a suggested mark for an answer. In Proctorly Examination, that’s all it is: a suggestion. The evaluator reads the answer, sees the suggested mark and decides, and they have the final say on every mark.
There are good reasons for keeping it that way:
- Accountability. A named evaluator is responsible for each mark, and that’s who an appeal panel will ask about.
- Fairness. An unusual but correct answer is judged by a person who knows the subject.
- Trust. You can tell students and faculty plainly that a person marked the script.
For each exam, you decide whether to use AI mark suggestions at all.
Why universities move to digital evaluation
Paper valuation comes with familiar problems. Answer books travel between centers and valuation camps, totals are added by hand, a second valuation depends on finding the right bundle, and results wait while someone reconciles marks. A digital evaluation system deals with each of these.
- Scripts stay where they are. After digitization, scripts are marked on screen, so the physical answer book doesn’t have to travel to each evaluator.
- Consistent marking across a large panel. Anonymous marking, multiple valuation passes and variance rules keep marks fair when many evaluators share one paper.
- No separate totaling step. The system records each mark and calculates the totals, which takes manual totaling errors out of the process.
- A trail for every mark. The audit trail shows who marked each script, in which pass and when.
- Faster to results. Marks go straight into results and committee approval on the same record, without an export.
- Revaluation that is easy to trace. Original and revised marks both stay on record.
We don’t publish a figure for how much faster your results will be, because that depends on your scripts, your evaluator panel and your rules. Ask us to model it on your own exam calendar.
CBSE on-screen marking: what it means for universities
In India, much of the search interest in on-screen marking comes from news about CBSE on-screen marking for board exam answer books. For the exact scope, classes and timelines, check CBSE’s own current circulars rather than news summaries.
For universities and colleges, the lesson goes beyond any one board. Once students and parents see large boards marking on screen, they expect the same from their university: anonymous marking, consistent second valuation and a clear answer when they ask how their script was marked.
Proctorly isn’t affiliated with CBSE, and this page doesn’t describe CBSE’s system. It describes how a university can run its own on-screen marking with the controls an appeal panel expects.
Online answers and hall scripts in one evaluation
Proctorly Examination is hybrid by design, so the same exam can run in a center and online with one seat plan and one set of results. Evaluation works the same way.
- Hall scripts are digitized with chain of custody and marked on screen.
- Online sittings run on the Proctorly core, proctored at the assurance level you choose.
- Handwritten working that online candidates photograph on a phone during the exam is attached to the question for the marker.
Typed answers from online sittings and digitized hall scripts can go through the same evaluator workflow, and every result ends up on one record.
What to check before choosing on-screen marking software
Any on screen marking software on your shortlist should give clear answers to these six questions.
- Chain of custody. Can the vendor show where each script has been, from the hall to the evaluator?
- Anonymity. Is the candidate’s identity hidden from evaluators by default?
- Valuation passes. Can you run more than one valuation and set variance rules for when marks differ?
- Evaluator identity. How does the system confirm that the assigned evaluator is the person marking?
- Who decides. If AI suggests marks, does the evaluator have the final say on every one?
- Results and revaluation. Do marks flow into results and revaluation on one record, or do you have to export them to a separate online marking system?
Frequently asked questions
What is on-screen marking?
It’s a way of evaluating exam answer scripts on a computer instead of on paper. Scripts are digitized and candidate identity is hidden. Evaluators mark the digital copy while the system records each mark and keeps an audit trail. In Proctorly Examination it also covers multi-pass valuation, variance rules, AI mark suggestions that the evaluator approves, and results on the same record.
How is on-screen marking done?
Scripts are digitized with chain of custody and allocated to evaluators with the candidate’s identity hidden. Evaluators mark on screen while a face check confirms who is marking. Where your rules require it, scripts get more than one valuation, and variance rules trigger another look when marks differ. Approved marks then move on to results, committee approval, publication and any revaluation.
Does AI mark the scripts?
No. AI can offer a suggested mark beside an answer, but the evaluator reads the answer and decides. The evaluator has the final say on every mark, and the audit trail records who marked each script and when. That keeps a named, accountable person behind every mark, which is what students and appeal panels expect.
Can on-screen marking handle both hall and online exams?
Yes. Proctorly Examination runs hybrid exams with one seat plan and one set of results. Hall scripts are digitized with chain of custody and marked on screen. Online candidates sit on the Proctorly core, and any handwritten working they photograph on a phone is attached to the question for the marker. All results end up on one record.
Is on-screen marking only for large boards like CBSE?
No. Boards have put on-screen marking in the news, but any university or college with a large evaluator panel gets the same benefits: anonymous marking, consistent second valuation, totals calculated by the system and a clear trail for appeals. Proctorly Examination is built for universities and colleges running their own semester evaluation.
