This document discusses assessment in content area literacy. It defines assessment and differentiates it from evaluation. Assessment should be an ongoing process that informs instruction, not a one-time event. Assessments are shifting from traditional methods like tests to more performance-based approaches. Effective assessments are standards-based, authentic, reflective, dynamic, and use multiple response formats to address students' varied strengths. Formative assessments like observations, retellings, self-evaluations and think-alouds inform instruction. Summative assessments include projects evaluated with rubrics and traditional tests. Authentic assessments in an elementary classroom include readers' theatre, reading groups, and writing workshops where teachers observe and provide individual feedback.
