  1. ECDL Test Development and Validation Process Paul Davis, Oxford University Computing Services Garry Cleere The European Computer Driving Licence Foundation Ltd.

  2. Test development process CAA Conference

  3. Syllabus Definition (Expert Opinion) CAA Conference

  4. Soft Test Characterisation • Non-threatening test experience • Predominantly performance based • Straight forward language • No trick questions • Coherent outputs • Sustains the metaphor of the driving licence • Ample time CAA Conference

  5. Forum score CAA Conference

  6. Test characteristics – reallife CAA Conference

  7. Forumduration of tests CAA Conference

  8. Mean duration CAA Conference

  9. Criticality (Core Item Identification) Exercises CAA Conference

  10. ModelTestsExercise • SMEs create 4 streams of tests • Spread core items across streams • Provide a reasonable coverage in each test • Provide syllabus coverage across streams • Average number of items CAA Conference

  11. REF. TASK ITEM MT 1 MT 2 MT 3 MT 4 3.1.1.1 Open (and close) a word processing application.  NE  NE NE  NE 3.1.1.2 Open one, several documents. 1 3.1.1.3 Create a new document (based on default, other available template). 1 1 1 1 ModelTests Grids Scheme CAA Conference

  12. Item Count 36 Items • Item Count dictated by coverage requirement • Dictated by congruency and criticality in tests • 100% Syllabus coverage throughout ECDL tests • Balanced, discriminating test profiles for Syllabus V.4 • Tests Syllabus Version 4.0 rigorously • High reliability in tests andbetween tests • Item Count standardisation in all Modules CAA Conference

  13. Result against completion time CAA Conference

  14. Cut Score /PassMark • Systematic approach and Industry based cut score technique (modified Angoff Method) • Underpinned by expert opinion • Cut Score exercises carried out for each module • Borderline Candidate, or Minimally Competent Candidate (MCC) • Meaningful Cut Scores based on profile of ECDL tests derived from ECDL V4 Syllabus • Item Count standardisation in all Modules • An auditable, standard cut score process • Common cut score across all ECDL core level modules, (M1 - 7) CAA Conference

  15. CutScoreExercises CAA Conference

  16. ModelTestsCollationandBalancing CAA Conference

  17. Characterisation Test Template Version 4.0 CAA Conference

  18. Item / Test Development Dependant upon: • Syllabus • Soft Test Characterisation • CTT • ECDL-F Evaluations • Outcome Probability Grids (expected pass rate from question) CAA Conference

  19. Item / Test Development CAA Conference

  20. Expert Review of Items / Tests • Syllabus Congruence • Syllabus Coverage • Compliance with CTT • Appropriateness of Item format • Technical Accuracy • Language & Clarity • Text Content CAA Conference

  21. Expert Review : ATES Systems • Test Presentation / Interface Features • Timing & Information • Appropriateness of ATES Test Content • Test Content • Marking Algorithm • Candidate Information and Guidance • Practice Tests • Documentation and Training Materials • ATES Technical Support • Reporting • Test Generation • Security Features CAA Conference

  22. Perceptions of tests CAA Conference

  24. Expert Review : Test Design / ATES Systems • ATES System Overview • ATES System Hardware Requirements • ATES Operating System Requirements • Other Software Requirements • Minimum Screen Resolution • Assistive Technologies • Screen Design and Visual Impairment CAA Conference

  25. Assembly and Administration of PilotTests • Tests are made available for Pilot Test activity • Qualitative analysis • Test taker and administrator observation sheets / questionnaires • Test data requirements Remember: • Across 4 streams for 7 tests across 100 countries and many languages. CAA Conference

  26. Pilot Tests Review Pilot Test results are reviewed by the ATES Evaluations Group. Any changes requested in the tests based on Pilot testing are then undertaken before the live certification tests are administered. To ensure statistical validity some pre-testing on the fly is used until results don’t change. Maintenance then takes over. CAA Conference

  27. EmpiricalEvidenceEvaluation ECDL Tests are evaluated and monitored on an ongoing basis by the ATES Evaluations Group using recognized psychometric measurements. CTT Version 4.0 - Test behaviour statement CAA Conference

  28. Ongoing Maintenance of Tests ECDL tests are monitored on an ongoing basis by the ECDL Foundation ATES Evaluations Group. Tests are updated in line with Syllabus revisions and also where test results or empirical evidence indicates that items or tests are not functioning in line with test behaviour parameters. CAA Conference

  29. ProcessStepsandtheValidityArgument • Documented process - expert opinion • Detailed test data reporting requirements • Data fed back to the ECDL Foundation • Industry Standard techniques • Process Loop • Valid ECDL Tests CAA Conference
