Internal Verification


Internal Verification is a process by which the Centre regularly samples and evaluates its assessment practices and decisions and acts on the findings, to ensure consistency, fairness and the maintenance of standards.

Models of Internal Verification


The Centre can operate one or more of a number of models, depending on the particular situation. All models must involve every tutor/assessor and all Certa provision. No individual can internally verify work that s/he has assessed. There must be an overall coordinator whichever model is chosen; effective models include:

  • A single Internal Verifier verifies the work of all assessors.
  • Designated assessors act as Internal Verifiers, each responsible for verifying the work of one or more other assessors.
  • All assessors act as Internal Verifiers using a ‘Round Robin’ approach; assessor A verifies for assessor B, assessor B for assessor C and assessor C for assessor A.

Verifying all assessment tasks

This may be done whenever the course ends in preparation for the next run. The Internal Verifier should check that each task is fit for purpose (see Assessment for further details). S/he should complete a verification record sheet for each assessment task, and provide feedback to the person(s) who devised the task. Required improvements must be completed before the task is used with learners. Although it is good practice to review tasks and update them, there is no need to re-verify tasks that are going to be used unchanged in the following year.

Verifying a sample of assessed work

Internal Verifiers should check samples of assessed work as close to the time they were assessed as possible. This is so that any action points can be implemented before the work is returned to learners. The Internal Verifier should look for evidence that:

  • the assessment task was pre-issue verified and that any changes required as a result were implemented
  • assessment decisions are fair and consistent
  • assessments meet the required level (as per the Ofqual Level Descriptors October 2015)
  • learners are given clear feedback that helps them improve
  • learner work is authentic
  • clear and accurate assessment records are maintained.

 Internal Verifiers should check the selected sample in three ways:

  • all assessment for an individual learner – to ensure assessment is appropriate, sufficient, consistent and complete
  • specific learning outcomes across a number of learners – to ensure that assessment is consistent for all learners
  • Level and credit value – to establish that standards are maintained across Units, assessors and sites, and, over time, continue to reflect the requirements of the assessment criteria.

The Internal Verifier should complete a verification report form for each piece of assessed work that is verified, to record the outcome and provide feedback to the assessor. Feedback should make clear:

  • whether the Internal Verifier agrees with the assessment decision or requires it to be changed
  • whether feedback to learners is of sufficient quality
  • how the assessor could improve her/his assessment practice

Please note that the Certa Quality Reviewer or External Verifier will need to see all internal verification records as part of annual Centre Monitoring.


The Internal Verifier (IV) – not the assessor – should specify the sample of assessed work that s/he wants to see. The minimum sample size is 10% or five portfolios, whichever is the greater. The Internal Verifier should increase the sample size if s/he is concerned about the standard of assessment, eg, at a particular site, or by an individual assessor. It is good practice to sample 100% of the assessments conducted by new assessors, or assessors new to Certa provision, until the IV is sure that their assessment consistently meets the required standards.

Whatever the size, the sample should be randomly selected, eg, every tenth name on the register starting with a different name each time.
