Marking your work & the role of the Assessment Boards

Who marks my work?

In accordance with the College Marking Framework, any staff member involved in marking your work will have the appropriate experience and expertise. The Assessment Sub-Board (details below) ensures that new examiners have the necessary guidance and support to carry out marking duties. 

Each examination script is carefully marked by two examiners from the department, then the marking checked by external experts. High importance summative coursework is also marked by two members of staff and checked by external examiners (e.g. projects). Where summative coursework counts for a small percentage of the total module marks (less than 20%), marking is done either by a member of staff or a trained PhD student (e.g. in labs), with oversight provided by the module leader who will examine a selection of the submitted pieces of coursework after the first stage of marking. Some multiple choice tests are marked using optical scanners and appropriate software under human supervision and scrutiny. Multiple choice KEATS tests are also marked automatically.


Details of the assessment methods for modules on joint programmes can be found on the respective student handbook pages:

Marking Criteria

It is important that you are aware of the marking criteria used by academics to mark assessments. The marking criteria provide guidance on the overall standards expected at different levels of your studies.

The Faculty of Natural and Mathematical Sciences has local marking criteria (internal webpage) in addition to the generic marking criteria of the College

Additionally, the Department of Mathematics employ a mark moderation process in order to ensure that students in the Department are judged fairly against the Faculty and College marking criteria.

Marking Framework

King’s is committed to an assessment process that is fair, equal and transparent and your work is therefore marked in accordance with the College Marking Framework.

Assessment Sub-Boards select the most appropriate Marking Framework model/s for each individual module. The individual module information pages in this handbook specify the marking models used for your assessments.

For modules taught in the Department of Mathematics, the most common marking models are Model 2 (for most written exams), Model 6 (for multiple choice components) and Model 1 (for project theses).


Marking model definitions

  • Marking model 1 – Blind double-marking

Blind double marking means that separate copies of the assignment are marked independently and anonymously, or the first marker makes no annotations on the work being marked so that the second marker examines all pieces of work as they left the student. Both examiners record their marks and comments separately and a final mark is determined.

  • Marking Model 2 – Double marking

Double marking means that all examination scripts and report/dissertation or other form of written assessment are marked by at least two Internal Examiners or by one Assessor and one Internal Examiner. Both examiners record their marks and a final mark is determined.

  • Model 3 – Double marking by retrospective sampling

Double marking by sampling means that all examination scripts or other form of written assessment are marked by an internal examiner. A second internal examiner then double marks a sample of the work already first marked, the sample being randomly selected from across the range of marks.

  • Marking Model 4 – Scrutiny

Scrutiny means that all examination scripts and other form of written assessment whose primary purpose is summative are marked by an Internal Examiner(s). A second examiner, who will have access to the grades and comments of the first marker(s), will scrutinise a sample of assessments to assure the quality of marking standards

  • Marking Model 5 – Single marking

Single marking is where assessments are marked by one examiner. This approach is useful when marking formative assessments and small parts of summative assessments. If this method is employed in summative assessment the following safe guards must be adhered to:

  1. no individual piece of work should contribute greater than 15 per cent to the overall assessment on a given module;
  2. any one examiner should not single mark work contributing to >50 per cent of the overall module
  • Model 6 – Online/computer based assessment 

This procedure is normally employed to mark multiple choice question papers. It would be expected that a clerical check would be carried out to ensure that the marks have been collated and assigned to the correct candidate.


For full details please see the College Marking Framework.

Role of the Assessment Boards

Faculty Assessment Boards and Programme Assessment Sub-Boards are responsible for ensuring examinations and assessment procedures under their remit are carried out in accordance with College, Faculty and Department regulations governing the programme. More information about the role of the Assessment Boards can be found on the Academic Quality webpages.

The members of your Assessment Board and Assessment Sub-Board can be found on the Internal Examinations Office webpages.  

External Examiners

External Examiners are appointed to ensure the quality and standard of the College’s taught awards. The External Examiners are experienced examiners who are academics at other institutions in the same subject area as the programme. They ensure that assessment processes are fair, rigorous and operated equitably. 

You can find out who the External Examiners for your Programme are on the Assessment Board Membership lists.

Students are not to make direct contact with external examiners, in particular regarding their individual performance in assessments. Other mechanisms are available such as appeal or a complaint if students have cause for concern.

External Examiners' reports

External Examiners' reports are available to read on the King's internal webpages.
