Test booklets are sold in packages of 25 booklets. Each package includes one Directions for Administration.

Students in Grade 3 mark their answers directly in the test booklet. A separate answer document is required for students in Grade 4. Answer documents may be centrally scored by the Riverside Scoring Service® or locally scored either by hand or through use of the Riverside Local ScoringPro™ software.

Cost per student for Year 1:
$13.49* for grade 3 and $11.14 for grade 4*. Included are: directions for administration; manual for scoring and interpretation; technical report and supplement; answer document; test forms; and basic scoring service.

Cost per student for subsequent years: $10.63 for grade 3 and $4.64 for grade 4 which includes the test forms and protocol.

* Per-student pricing assumes 1 of each of the identified manuals for every 25 students.

Computer access is required for full use of product services.

Testers will require less than 1 hour of training.

Accommodations: Test accommodations can include out-of-level testing, individual/small group administration, and repeated directions, all of which will not impact the validity of the norms. In addition, Grade 4 students who, for whatever reason, have difficulty maneuvering between test booklet and answer sheet may mark their answers directly in the test booklet.

Training manuals are available and should provide all implementation information. Ongoing technical support is available through toll-free telephone support and Riverside Field Staff.

The Gates-MacGinitie Reading Tests are norm-referenced screeners designed to provide a general assessment of reading achievement ability for individual students. The screening content is sensitive to the wide range of reading abilities and special interests of students.

For Grades 3 and 4, each test level of the GMRT consists of two sections: Vocabulary and Comprehension. The first section of the GMRT is a test of word knowledge. It measures the student’s ability to choose the word or phrase that means most nearly the same as the test word. Selected words are suited to each grade level. The second section of the GMRT at these levels consists of reading passages written in a variety of writing styles related to various content areas. The student’s task is to choose the correct answers which will demonstrate both literal and inferential comprehension of questions about each passage.

The GMRT takes 55 minutes to administer Tests are centrally scored.

Two alternate forms are available for grade 3 and grade 4.

Available scores include: raw; percentile; grade equivalents; stanines; normal curve equivalents; equated; lexile; subscale/subtest; composite; and extended scale.

The number of questions a student answers correctly on any test is the student’s raw score. In itself, a raw score for a test tells almost nothing about student achievement. Composite scores are obtained by adding the raw scores from the subtests together.
