TerraNova 2/CAT 6

The TerraNova 2, also known as the CAT 6, is a nationally-recognized, norm-referenced test that meets most states’ annual testing requirements. The TerraNova/CAT 6 was normed in 2005, and replaces the CAT 5. It provides a series of tests that are easy to administer, stimulating to take, and most importantly extremely accurate in their assessment of student achievement. This test is the updated CAT 5.TerraNova 2/CAT 6 tests can be rented by homeschoolers and private & public schools (on school letterhead).

    TerraNova 2/CAT 6 Practice Tests (Grades K-8)

    TerraNova Practice Test KitThese short practice tests (6-8 pages with about 2-5 questions per subject area), published by the TerraNova 2/CAT 6 publisher, will give students an idea of what to expect on test day and increase their confidence in taking the test. A few practice questions (about 2-5) are given in each of the subject areas, the answers to which are provided in the Practice Test Directions for Administration booklet. Directions for Administration read like a script. Students mark their answers in bubbles like on an actual test. Practice Tests are untimed but can be completed in 40 minutes. For the most effective use, the Practice Test should be administered one to two days before the test date. 

    TerraNova/CAT 6 Practice tests may be administered by anyone. 

    These practice tests are especially recommended for students testing for the first time. They are also good for when students transition from marking answers in the booklets to filling out a separate answer document (starting with the TerraNova/CAT 6 Level 14 (Grade 4)). Practice tests are available in kits or as individual student practice tests.

    *Student Practice Tests for GRADES K, 1, & 2 (Levels 10-12) CANNOT be administered without using the Directions for Administration.

    Yes, the TerraNova/CAT 6 is a timed test and takes from one and one-half hours to five and one-half hours of actual working time for the students to complete, depending upon the grade level and the test taken. All levels of the TerraNova/CAT 6 are timed. No section for the TerraNova/CAT 6 is longer than 40 minutes. No more than two or three tests should be given in one day. The tests should be spread out over a 3 or 4 day period. View what is tested on each level and the completion times for each section.

    The TerrraNova/Cat 6 is a nationally normed achievement test. Achievement tests measure skills that are learned in school and address specific content areas such as reading and mathematics and measure academic progress. Your child’s scores are compared to the scores of other children who have taken the test, the norming population for the test. There is no direct correlation between the number of correct answers and the percentiles reported. If, for example, a student scores at the fifty-seventh percentile, it indicates that a student scored higher than fifty-seven percent of students who took this test in the national sampling group for his grade level, not that the student got fifty-seven percent of the questions correct.

    The TerraNova, Second Edition, known as the CAT 6 is the 6th edition of the California Achievement Test. It tests K-12 students in the areas of Reading (Grades K-12), Language (Grades K-12), Math (Grades K-12), Social Studies (Grades 1-12) and Science (Grades 1-12). It is available in Complete Battery or Survey form. Also included is the Plus Test, which tests Word Analysis (Levels 11-21/22), Vocabulary (Levels 11-21/22), Language Mechanics (Levels 12-21/22), Spelling (Levels 12-21/22) and Math Computation (Levels 11-21/22). Click the following link for a detailed document of the TerraNova Scope & Sequence.

    The Survey edition is a shortened form of the TerraNova/CAT 6 that is composed from a subset of items found in the Complete Battery. Administering the Survey form of the test takes about half as much time as the Complete Battery. Both the Survey and the Complete Battery measure the same content areas, but the Survey has fewer questions. The Survey is a shorter test and does not provide the breadth of coverage for each objective that is found in the Complete Battery. The Plus tests are the same for both forms of the test.

    The publisher suggests that you should use the Complete Battery when making high stakes decisions (such as acceptance into an academic program), when you have three or more hours to administer a test, or when the results of a test are likely to be challenged. Use the Survey if the testing time is short, if you are screening for a program entry or exit, or using this as a pre/post test model for which the Survey would be your post test. The Survey w/Plus is offered for grades 2, 3, 4, and 6-12. The Complete Battery w/Plus is offered for grades 1-12 and the Complete Battery is offered for grade K.

    The Plus section is additional math, reading, and language questions that are all optional.

    The TerraNova/Cat 6 test is designed so that almost all students have time to complete the test. The percentage of students completing the final question in each section of each subtest varies by grade and format. Approximately 94-99% of students complete the tests in the time allotted. Please read and adhere to the testing directions for the timing of each test section.
