Scores from non parallel measures can be equated through the use of:
1. Classical test theory
2. Empirical criterion keying
3. Item response theory
4. Ipsative measures

Item response theory or latent trait theory...calculates to what extent a specific item on a test correlates with an underlying construct. Looks at performance on a test item as rep degree to which have latent trait. Get hard stat ?, have hi stat ability. So can use it to compare performances in 2 measures that have different types or number of items or are scored differently. Use item response theory to develop individually tailored adaptive tests in which to answer one ? In a domain which determines if another ? Will be asked. Such tests have least number of items needed to assess performance.
