Bongo LLP are actively developing a range of test delivery systems. With an understanding of psychometrics and test validities at the core of everything we do, we are ideally placed to carry out this work again both for external clients and for use within our own product range. Bongo LLP has designed and developed the complete solution from concept to delivery. We are currently working with our clients to ensure all of the following validities:

• Face Validity
• Statistical Validity
• Construct Validity
• Content Validity
• Predictive Validity
• Concurrent Validity
• Convergent Validity
• Discriminant Validity

At the core of any automated test delivery systems is a set of rules. Our team is also currently involved in the development of a number of rules bases, which are at the core of our involvement in adaptive test engines. We are able to offer clients an effective adaptive test delivery system. International Curriculum and Assessment Agency (a UK based Examination Awarding Body) is one of our many clients.
