What is the ERB?

There is no test named “the ERB.” Although parents, teachers, and school administrators often use this term to describe all ERB testing programs used by their school. Each of ERB’s four testing programs has its own name and is designed to evaluate content and skills taught in each grade level.

The “ERB” test that some students in Los Angeles take is the Comprehensive Testing Program, or CTP 5. Other students take the comparable Stanford Achievement Test Series, Ninth Edition (Stanford 9, SAT-9). These tests comprise ten levels that span grades 1 through 11. Content of CTP 5 and SAT 9 captures mathematics, with test score reports that organize items into curriculum-specific content clusters.

Can students receive accommodations?2020-05-27T01:07:42-07:00

In general, ERB does not proscribe the accommodations that a school may provide to a student on the CTP. These decisions are left to the discretion of the school. Schools are typically advised to follow any existing accommodation protocol that a student may receive for other in-class assignments or tests. Schools should follow a student’s 504 plan (where available) or IEP plan, where applicable, for guidance on what accommodations to provide.

What is the purpose of the ERB (CTP)?2020-05-27T01:06:31-07:00

The purpose of ERB is to assess student growth and performance at the time of testing. This enables the school to identify strengths and weaknesses at an individual and group level. The ERB is considered a “low stakes” assessment, intended to help teachers and administrators make decisions about curriculum and classroom instruction.

Where do I take the ERB (CTP)?2020-05-27T01:05:40-07:00

The ERB is administered by your student’s school and your school makes all decisions about test schedules, testing options, and reports. Families should direct any questions they have about the ERB to their school.
