"This second edition of "Mathematics Assessment and Intervention in a PLC at Work" by Sarah Schuhl, Timothy D. Kanold, Mona Toncheff, Bill Barnes, Jessica Kanold-McIntyre, Matthew R. Larson, and Georgina Rivera provides updated tools and additional resources for education professionals seeking to implement the professional learning community (PLC) approach in their schools. The PLC at Work method models how schools and districts can use team collaboration to build a more equitable learning experience for students. By creating common criteria for scoring student proficiency and agreeing on the rigor of curriculum and assessment, educators can ensure students school- and districtwide receive comparable instruction and feedback. Augmented with personal anecdotes and opportunities for team reflection, this edition includes new tasks, common assessments for various grade levels, self-assessment examples for student reflection, and revised rubrics, as well as how to score end-of-unit assessments using a proficiency scale"--
