Used data from a classroom-based performance assessment to document the impact of participation in a short-term educational program, the LinkUP! program. Participants were students in 32 classes in fourth, fifth, and sixth grades. The study provides an example of the use of classroom-based performance data for program evaluation purposes. (SLD)

The national examination systems of Ethiopia and South Australia are compared with an eye toward identifying problems in the Ethiopian system.

There is presently much disagreement about how students should be evaluated effectively to determine their progress. Some common methods are reviewed, including standardized tests and performance-based evaluation such as portfolios. Continuous experimentation is necessary in the effort to develop better measurement approaches. (SLD)

The development and administration of practical skills tests in science as part of the Second Science Study of the International Association for the Evaluation of Educational Achievement are described. Scoring and sampling for Hungary, Israel, Japan, Korea, Singapore, and the United States are reviewed. (SLD)
