International Test Commission guidelines for test adaptation: A criterion checklist.

Area of Science:

• Psychometrics
• Cross-cultural psychology
• Educational assessment

Background:

• International Test Commission (ITC) guidelines aim to enhance test adaptation quality and score comparability across cultures.
• These guidelines are not consistently implemented due to their broad scope, hindering practical application.
• A need exists for a practical tool to facilitate the implementation of ITC recommendations.

Purpose of the Study:

• To develop an evaluative criterion checklist for test adaptation.
• To operationalize International Test Commission (ITC) guidelines into practical criteria.
• To create a model for assessing the quality of test adaptations.

Main Methods:

• Operationalized each ITC guideline into specific criteria with defined accomplishment levels.
• Reviewed the initial checklist with a panel of 12 experts in testing and test adaptation.
• Applied the refined checklist to two distinct tests using two independent reviewer pairs.

Main Results:

• A final evaluative checklist comprising 29 criteria was developed.
• The criteria cover all essential phases of test adaptation: planning, development, confirmation, administration, score interpretation, and documentation.
• The checklist provides a structured approach to evaluating adaptation quality.

Conclusions:

• The proposed evaluative checklist is expected to improve the quality of test adaptations.
• This tool facilitates the practical application of ITC guidelines.
• It serves as a valuable resource for researchers and practitioners involved in test adaptation.
