2017 key stage 2 Item Validation Trial (IVT)
The SQA is working on behalf of the Standards & Testing Agency (STA) to conduct the 2017 Item Validation Trial (IVT) at key stage 2, which will take place between 15-26 May 2017. Participation in the trial is by invitation only and STA will draw a representative sample of schools with age-appropriate children. From 2017, participation is statutory for those schools selected by STA for participation in the national curriculum tests trial.
Taking part in this year’s key stage 2 IVT will help you to prepare for the national curriculum tests. You will also have an opportunity to influence the content of future key stage 1 tests, helping to ensure that they provide valid and reliable assessments.
The trial will test the reliability of test questions which, depending on their performance, will be used in future national key stage 2 tests. The trial is aimed at testing the performance of individual questions rather than the performance of any pupil, and will help establish the following:
- clarity and accessibility of the test materials and questions
- technical functioning of the questions
- clarity and accuracy of the mark scheme.
Trialling the questions means that schools can have more confidence that the results of national curriculum tests will be valid and reliable.
