• Dual Language Curriculum-Based Measures (CBMs)

    What is a Dual Language CBM?

    When is it administered?

    CBMs are administered three times per year in the Fall, Winter, and Spring.

    View the district testing calendar for the current year's testing windows.

    How is it administered?

    • PPS-created dual language CBMs are paper-based
    • The test takes about 40-60 minutes

    How are the results used?

    Teachers can use scores to

    • Personalize learning to match students' early literacy needs
    • Identify students who need additional support for early reading skills
    • Recognize students who are making progress

    CBMs are used as a screener initially to indicate if a student may need more focused instruction and then as a formative assessment throughout the year so that teachers can adjust their teaching, if needed.

    Who requires it?

    This test is required by Portland Public Schools for students in dual language immersion programs (except Spanish).
