CMAS Performance Levels, Cut Scores, and Test Design

Performance Level Descriptors (PLDs)

PLDs provide details about the specific grade-level content area concepts and skills typically demonstrated by students within a CMAS performance level. The met and exceeded expectations levels are considered on track to being college and career ready.

Performance Level Cut Scores

Students taking CMAS assessments receive an overall scale score. During the standard setting process, educators used scale scores to set cuts for each performance level based on the specific content that students should be able to engage with at each performance level.

Test Design

Information such as frameworks, high level blueprints, scoring rubrics, and evidence statements and standards that appear on the CMAS assessments.

State Assessment Accommodations

Accommodations are practices and procedures that provide equitable access during instruction and assessment for students who have a documented need, including students with a disability and English learners. In order to use accommodations on state testing, accommodations must be documented in the student’s IEP, 504, or EL plan. Additional information is available on the state assessment accommodations webpage.

Information relating to the use of accommodations during instruction is found on the CDE Office of Special Education webpage.
