Diagnostic Testing


One of CLC's specialties is educational diagnostic testing, which we personalize for each student. By using nationally standardized assessments, administered by a certified psychologist or educational diagnostician, CLC can determine individual learning requirements, grade equivalents, specific subject weaknesses and strengths, and the learning style that will be most effective for each student.

And we don’t simply test the students once – we regularly re-test them to measure their progress. This allows us to update the Individual Education Plan (IEP) on a continual basis. In addition, our Director will, upon request, accompany parents and students into the school system to advocate for the student and to ensure that his or her educational needs are met.

The cognitive, psychological achievement, preschool, and counseling tests CLC uses include:

*The Wechsler Intelligence Scale for Children - Third Edition (WISC-III). This diagnostic test produces results from 13 individual subtests, yielding a full-scale IQ score, a Verbal IQ score, and a Performance IQ score; these provide information about a student’s strengths and weaknesses in both the language and overall performance areas. Examiners can also obtain clinical information by analyzing the student’s performance on specific subtests and groups of subtests.

*The Woodcock-Johnson Psycho-Educational Battery - Revised (WJ-R). An individually administered, multiple-skill battery, this assessment can be used on students ranging in age from 3 to 80 years old. It consists of two separate parts: 1) tests of cognitive ability, and 2) tests of achievement. The latter indicate if a student is not able to achieve because he/she is cognitively impaired (low ability), or if he/she is able to achieve but is simply not performing up to potential.

With subtests that include word and picture recall, visual-auditory learning, oral vocabulary, sound patterns, and listening comprehension, the WJ-R can also provide information about a student’s learning style, long and short-term memory capabilities, processing speed (for example, if the student requires extended time periods to accomplish a specific task), auditory and visual discrimination; abstract reasoning skills, and a number of auditory and visual processing problems.

*The Nelson-Denny Reading Test. With subtests in vocabulary, reading comprehension, and reading rate, this test provides more in-depth information about the specific nature of a reading problem than the WJ-R. Another often-used assessment in this area is the Woodcock Reading Mastery Test.

*The Key Math - Revised. This diagnostic provides specific information on basic mathematics skills for students up to the 8th grade. The Stanford Diagnostic Mathematics Test can determine the nature of arithmetic difficulties in all grades from K-12.

Sometimes diagnoses must probe more deeply; therefore, CLC also has a battery of standardized psychological tests available, should they be needed. These tests are, of course, administered and evaluated by certified and licensed staff psychologists, who are also ready to provide psychotherapy services, if warranted.
