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.

Smarter Balanced Assessments
California uses annual measures from the Smarter Balanced Assessment Consortium to evaluate English language arts and mathematics learning for students in grades 3 through 8 and 11. Results from the 2015 Smarter Balanced Assessments were released in September 2015. The California Department of Education provides access to results for all counties, districts, and schools here. Results can be disaggregated by grade, subject and significant school subgroups. Descriptions of the knowledge, skills, and processes that are demonstrated by students with this assessment are described at the Smarter Balanced Assessment Consortium website.

CAASPP Logo 2015 SBAC Results for Sonoma County Districts & Schools | Link
This page provides annual Sonoma County results for the Smarter Balanced Assessments in English Language Arts (ELA) and mathematics, showing the percent of students who were proficient, or met or exceeded the standards.

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)
The Early Assessment Program (EAP) is a collaborative effort of the State Board of Education, California Department of Education, and California State University. 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. Support for 2015 EAP results with resources for student advisement can be found here. EAP Information for districts and schools prior to 2015 can be found here.

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.
