McNamee and Chen describe the Bridging assessment system they developed to measure performance on specific learning tasks for pre-K through 3rd-grade students. Bridging assesses an individual student's skill level on learning tasks in five curricular areas: language arts and literacy, visual arts, mathematics, science, and performing arts. The assessment tool includes a detailed 10-level rubric for each task. The authors give examples of how teachers in Head Start classes in Chicago used Bridging to assess particular students and made specific changes in how they taught those students as a result of the assessment.
