This study employs the 4-parameter logistic item response theory model to account for the unexpected incorrect responses or slipping effects observed in a large-scale Algebra 1 End-of-Course assessment, including several innovative item formats. It investigates whether modeling the misfit at the upper asymptote has any practical impact on the…

Purpose: Based on the general formula, which depends on the length and difficulty of the test, the number of respondents and the number of ability levels, this study aims to provide a closed formula for the adaptive tests with medium difficulty (probability of solution is p = 1/2) to determine the accuracy of the parameters for each item and in…

Performance assessment is reviewed as an emerging form of alternative assessment, focusing on how it has been defined in the research literature, the criteria for evaluating its authenticity, the measurement of process and product, and the link between assessment and instruction. Three important dimensions that must be considered in describing…

Many state and local entities are developing and using performance assessment programs. Because these initiatives are so diverse, it is very difficult to understand what they are doing, or to compare them in any meaningful way. Multiple-choice tests are contrasted with performance assessments, and preliminary classifications are suggested to…
