CTP Test (Comprehensive Testing Program) from ERB

Students in Grades 1 through 11 take the CTP® (Comprehensive Testing Program) assessment. This is a test for high achieving students given at private and public schools nationwide. It is not one test, but a battery of sub tests consisting of a series of multiple-choice and optional constructed-response questions. It is administered in either fall or spring. During the fall window, the school will usually test at one grade level below the grade the child is in as they are testing for mastery of content knowledge from the previous year. For example, a child in Grade 4 will most likely test at Level 3 during the fall window. During the spring window, the school will most likely test at the same level as the grade the child is in as the school is testing for content knowledge of the current year. For example, a child in Grade 6 will test at Level 6 during the spring window.

Level 1Level 2Level 3Level 4Level 5Level 6Level 7Level 8
Spring to Fall Grades:1 to 22 to 33 to 44 to 55 to 66 to 77 to 88 to 9

CTP 5 was developed in 2018. The main difference between this test and its predecessors is that it assesses not only content-based curriculum performance but also has questions with increased complexity and critical thinking skills. Each question is assigned its own DOK (Depth of Knowledge) level.

English Language Arts:

DOK 1 – requires student to recite facts or use simple skills and abilities.

DOK 2 – requires student to both comprehend and process text. Analysis and inference are required for this level of question. Questions at this level may include these words: collect, compare, classify, display, infer, interpret, organize, and summarize.

DOK 3 – requires the student to have depth of knowledge. Questions require the student to show understanding of ideas in text and also be able to explain, generalize, or connect ideas.

Mathematics and Quantitative Reasoning:

DOK 1 – requires student to recite math facts, know basic math language, and classify objects.

DOK 2 – requires the student to exhibit basic application of math skills and concepts. Questions require the student to interpret the material to formulate an answer. They will need to decipher the information and use their conceptual knowledge to choose the appropriate procedure to formulate an answer. This could require two or more steps in the decision-making process. Questions at this level may include these words: compare, collect and display data, estimate, and organize.

DOK 3 – requires strategic thinking. Questions will require reasoning, planning, deciphering, creating a plan or sequence of steps to approach and solve the problem.

Do you have the CPT 5 test? That is what the new school we are attending says they will be testing with this year. Thank you for your time.


Hi, I would also like to know if you have CTP 5 tests. Thank you.

We do not currently have a page dedicated to the CTP-5, but it is on our To Do list and we do have some similar materials we can recommend from our site. If you are a member, please email to receive these recommendations. This is not a good forum for information sharing as it does not allow graphics.
Thank you,
