CAT/6 TerraNova 2nd Edition

Bayside now offers a more recently published test series than the now-discontinued CAT/5 or CTBS. The CAT/6 TerraNova 2nd Edition, published in 2000, was re-normed in 2005.

This is the test of choice for the do-it-yourself homeschool! It is valid for use not only in NC but in other states that require more recent test norms.

We offer the Complete Battery for Kindergarten (Level 10), the Complete Battery Plus for Grade 1 through Grade 12, and the Survey Plus for Grades 2-4 and 6-12. (There is no Survey available for Grades K, 1 or 5).

These are the most complete, extensive and up-to-date tests available for unrestricted homeschool use.

Level 10, Kindergarten, includes Reading/Language Arts and Mathematics.

Levels 11-21/22 (Grade 1 through Grade 12) include Reading/Language Arts, Mathematics, Science, Social Studies, plus Word Analysis (Levels 11-13), Vocabulary and Mathematics Computation (Level 11 & up), and Language Mechanics and Spelling (Level 12 & up).

Level 11 (Grade 1) students need to read well and understand simple stories, although much of this test is administered orally.

The CAT/6 is your choice for better scoring reports. Its more recent 2005 norms are preferred in many states.

Compared to the CAT/5, the TerraNova tests are more current in their presentation. Themes carry through the entire combined Reading and Language Arts Sections.

CAT/6 tests for Grades K-8 offer an optional $5 test familiarization (not skills building) Practice Exercise.

The cost of the CAT/6 TerraNova2 is $48 per student for Grades K-3 and $43 per student for Grades 4-12 (using separate answer sheet). Bubble-in student test books are available for Grades K-3 for $15 per test. See the ordering information page for details on placing your order.


The Test of Cognitive Skills is a one hour long aptitude, or intelligence (IQ), test that measures thinking abilities. It is available for students from 6 years 8 months to 18 years.
The TCS®/2 score is the Cognitive Skills Index (CSI) in a range from 58 to 141+ based on a mean of 100 derived from the four subtests Sequences, Analogies, Memory and Verbal Reasoning. This test does not meet state achievement test requirements.
The TCS is administered and scored separately from any form of the TerraNova. Order by Grade Level (2-12) for $55 per student.
