At the Laboratory Schools, teachers assess students by observing and interacting with them in the classroom, evaluating their day-to-day classroom work and homework assignments, meeting with their parents, and administering standardized tests.

Standardized testing at Lab is viewed as only part of the profile of students; it gives teachers a snapshot of each child’s strengths and difficulties. Standardized tests are designed to give a common measure of students’ performance. Since standardized tests are given to large groups of students throughout the country, a common standard of measure is derived. Lab teachers and administrators may use this information to tell how well school programs are succeeding or to learn more about the skills and abilities of individual students.

Grades 3 and 4, 6 and 8 --ERB/eCTP TEST

The Comprehensive Testing Program (CTP) is an achievement test, designed to measure what students have already learned in school. At Lab, we administer the electronic eCTP version of the Electronic Records Bureau (ERB) test. Included are sub-tests in English language arts, mathematics, and verbal and quantitative reasoning. Lab administers the online eCTP to third, fourth, sixth, and eighth graders in the fall or spring of the year.


The Retired ACT Test is a curriculum-based achievement readiness test provided by Academic Approach. The achievement tests measure students’ skills and abilities in English, mathematics, reading, and science. This April, Academic Approach administers the practice ACT to students in grade ten. Currently, the pencil and paper version of the test is administered.

Grades 10 and 11 --PSAT TEST

The Preliminary SAT/National Merit Scholarship Qualifying Test, the PSAT/NMSQT, is a program co-sponsored by the College Board and the National Merit Corporation. The achievement test measures students’ skills and abilities in critical reading, mathematical problem- solving, and writing. In the fall of each year, Lab administers the PSAT to students in grades ten and eleven. Currently, the pencil and paper version of the test is administered.
