Summative Data

The goal of summative assessment is to evaluate student learning at the end of an instructional period by comparing it against a standard or benchmark. States and districts frequently use summative data to evaluate instruction programs, gauge progress, and analyze demographic trends to improve student learning. This page lists common metrics used to gather summative data among schools in Sonoma County.

SBAC Reporting System | Overview Document (pdf) | Overview Video
Results from the 2015 Smarter Balanced assessments will be released to the public in August 2015. SBAC has issued a preview of what their reports will look like for districts/educators and parents/students. There will be four Achievement Level Descriptors (ALDs) in the reports. Outcomes will be reported as Level 1, Level 2, Level 3, and Level 4. The ALDs are text descriptions of the knowledge, skills, and processes that are demonstrated by students in each level. Learn more about achievement levels and the SBAC website.

CELDT Data Analysis | Link
This resource page, Electronic Tools for CELDT Analysis, was developed to help districts access and analyze the electronic data from the annual CELDT administration. It includes a video showing how the CELDT data can be analyzed using Microsoft Excel, resource files and guides, and related links.

Early Assessment Program (EAP) | Link
The Early Assessment Program (EAP) is a collaborative effort of the State Board of Education (SBE), California Department of Education (CDE), and California State University (CSU). The program provides opportunities for students to measure their readiness for college-level English and mathematics in their junior year of high school so that they can improve their skills during their senior year.

STAR Legacy Reports STAR Legacy Reports | Link
The STAR Legacy Reports page on the SCOE website provides school-by-school statistics from the STAR tests administered between 2009 and 2013. Users can look up student demographics, percent proficient, and similar schools ranks for Sonoma County schools and see the data over a five-year period. Please note that STAR Legacy Reports cannot be compared to the results from Smarter Balanced Assessments because the two systems measure student learning against different standards.
