educators / Comprehensive Assessments / CTP


For Grades 1-11

The Comprehensive Testing Program (CTP) is a rigorous assessment for students in Grades 1-11 covering reading, listening, vocabulary, writing, mathematics, and science. Verbal and quantitative reasoning subtests are part of the CTP beginning in Grade 3. The CTP helps educators assess content specific, curriculum-based performance alongside reasoning ability and conceptual knowledge.

Multiple Norm Groups Available

Compare student performance and growth against similar students via national, independent, international, association, and district norms.

Easy to Implement

Quickly purchase assessments and manage test administrations online via our dedicated Comprehensives Portal, with support always available from the ERB experts.

Flexible Administration Options

CTP is available in both paper and online formats, and can be administered to students in-school or remotely to students at home. 

Actionable + Timely Reporting

CTP results are available quickly, and can be meaningfully explored in our dynamic new ERB 360 Access platform to inform instruction and help students achieve learning goals.


Starting in Grade 3, separate CTP reasoning and achievement subtests provide greater insight into each student’s learning growth, assessing attained knowledge alongside reasoning.

The kids loved doing the tests online...the teachers were able to establish friendliness with the tests; the reports…are accessible, and we are already ‘curricularizing’ what we’ve derived from the kids’ performance. Thank you so much for guiding us through the process.”

On Paper or Online

CTP was designed to meet every classroom's needs with flexible online or paper administrations. Test students individually, in small groups, or as whole classes–with CTP, it's easy to set up test administrations on-demand.

Assess What Matters

With CTP, you can choose which subtests to implement to measure what matters without overburdening students. It's now easier than ever to check in with your students academically, with the same rigor and reliability you expect from ERB.

Here When You Need Us

The ERB Support Support Center is on call to support you in scheduling test administrations, interpreting reports, and more. We can help make the assessment process stress-free so you can focus on what's most important: your students.

CTP Gets a Power Boost

Take your testing program to the next level with Milestone Assessments, the new complement to CTP. These short interim assessments let you track progress across the school year - leading up to or after CTP - for more targeted interventions and better curriculum design.

With CTP, educators can pick and choose the subtests that are important to their schools. Available* subtests include:
  • Auditory Comprehension
  • Verbal Reasoning
  • Vocabulary
  • Reading Comprehension
  • Writing Mechanics
  • Writing Concepts & Skills
  • Word Analysis
  • Quantitative Reasoning
  • Mathematics 1
  • Mathematics 2
  • Algebra 1
  • Science
*Subtests vary depending on the level being tested.


In general, ERB does not prescribe the accommodations that schools may provide to students taking the CTP or Milestones. These decisions are left to the discretion of each 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  or IEP plan, where applicable, for guidance on what accommodations to provide.
