Network participants reviewed district and site level data to identify strengths and gaps in the quality of assessments. This allowed participants to ensure existing assessments provide valid and reliable data needed to diagnose student needs and monitor progress. Districts will address data findings with action oriented steps to identify priorities or an identified problem of practice. With the roll out of the English Learner Proficiency Assessment for California (ELPAC) and English Learner Progress Indicator (ELPI), the PLN will also examined assessment practices and progress monitoring of EL students. Ultimately, the purpose of the PLN will be driven by the need to decrease the gap in student achievement through the expansion of formative and summative assessment data review practices, at the district, school and classroom levels.
