CTB's proven standardized achievement products help educators meet the challenges of today's demanding assessment environment.


Informed instruction is critical to achieving proficiency in your schools. CTB/McGraw-Hill helps educators improve student achievement with a full range of standardized achievement tests and reporting solutions.

Achievement tests are designed to measure the things that a student knows and can do.
A well planned, comprehensive assessment program built upon a quality test provides valuable information about students that can support teaching in many areas, including:
• Evaluation of Student Progress
• Needs Assessment
• Instructional Program Planning
• Curriculum Analysis
• Program Evaluation
• Class Grouping
• Administrative Planning and Direction

A sound assessment and evaluation program reinforces educational decisions.
It can positively impact individual students as well as parents or guardians, groups or classes of students, schools, and commun-ities. Test data can be used to:
• Aid teachers and administrators in    improving instructional plans
• Keep parents informed about their    children's academic progress
• Inform the community of the    general progress being made by a    school or school system

Information you can trust.
Critical uses of test results place a heavy responsibility on the test publisher, who must ensure that the results are accurate and that clear, reliable information about the interpretation of results is provided. CTB welcomes this responsibility and works to produce quality achievement tests that provide the most valid and reliable information possible.
