CTP Test (Comprehensive Testing Program) from ERB

What is the CTP Test?

The Comprehensive Testing Program (CTP) developed by the ERB (Educational Records Bureau) is a test designed to collect basic information about your child’s achievement in these key areas: listening, reading, vocabulary, writing, and mathematics. The CTP is often referred to as the ERB test even though the ERB is actually the publisher and not the name of the test itself.

Verbal Skills

The Verbal portion of the CTP 4R test was created to assess the development of reading and language skills necessary for effective communication both in academic settings and in the world beyond the classroom.

Here are the skills covered:

  • Word Analysis (specifically phonemic awareness for younger children and decoding skills through all grades)
  • Auditory Comprehension
  • Reading Comprehension
  • Writing Mechanics
  • Writing Concepts and Skills
  • Verbal Reasoning
  • Vocabulary

Mathematics Skills

The Mathematics portion of the CTP 4R includes mathematics achievement, constructed response, quantitative reasoning and Algebra I tests, according to the child’s level. These tests include questions to assess your child’s conceptual understanding, procedural knowledge, and problem solving.

Here are the skills covered:

  • Number and Operations
  • Algebra
  • Geometry
  • Measurement
  • Data Analysis and Probability

Karen Quinn, the Testing Mom, breaks it down for you below.

The Comprehensive Testing Program 4R (CTP 4R Test) is an achievement/reasoning test that many independent schools around the country use to evaluate children for private school entry. It was developed by the ERB (See * below). It can be administered in an ERB office or at a school. There are 10 levels for this test, grades 1 – 11. In the elementary grades, children take the test under untimed conditions. Answers may be marked in a test booklet, or the test may be taken online.

Skill Assessment

CTP 4R covers the following:

  • Reading
  • Listening
  • Vocabulary
  • Writing
  • Science (online only)
  • Mathematics

Verbal and quantitative reasoning subtests are part of the CTP 4R beginning in Grade 3. The CTP 4R helps compare content specific, curriculum-based performance to the more conceptual knowledge-base found in reasoning tests.

Levels 1 and 2 of the test assess math and reading comprehension, along with word analysis and listening skills. At level 3 (beginning with spring testing) the test measures math and reading comprehension, along with verbal reasoning, quantitative reasoning, writing and vocabulary.

In 2018, the CTP 5 was launched. It includes many of the 4R materials, but also includes items at a higher depth of knowledge level, more conceptual understanding and problem solving in math and in language arts, an increased complexity, including nonfiction and inter-disciplinary content.

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,
