The Kaufman Test of Educational Achievement (K-TEA)

The Kaufman Test of Educational Achievement (K-TEA) was designed by Alan S. Kaufman & Nadeen L. Kaufman in 1985 and published through the American Guidance Service (Kaufman & Kaufman, 1985). Kaufman Test of Educational Achievement is a well-conceived and carefully constructed educational achievement test that was normed on a national sample of 2,476 students in grades 1 though 12. (Kaufman, A. S., & Kaufman N. L. 1985).

There are two overlapping forms included in the Kaufman Test of Educational Achievement (K-TEA): Comprehensive and Brief. The Brief Form tests reading, mathematics, and spelling. The Comprehensive Form measures more specific abilities, such as, reading decoding and comprehension, mathematics applications and computation, and spelling (Kaufman & Kaufman, 1985).

Norm-referenced measurements are included in both varieties of the Kaufman Test of Educational Achievement (K-TEA). The Comprehensive Form supplies criterion-referenced assessment data to analyze the students' errors in each subtest. Additionally, all standard scores in both forms are set at a mean of 100, with a standard deviation of 15; this allows for comparisons between the K-TEA and previously obtained standard IQ scores (Kaufman & Kaufman, 1985).

The Kaufman Test of Educational Achievement is a norm-referenced test; individually administered to measure the achievement of students enrolled in grades 1 through 12. The K-TEA is presented on an easel with only one or a small number of items per page, requiring (60-75) minutes to administer (Anastasi, & Urbina, 1997). Items are not multiple-choice and are focused on the areas of reading decoding, reading comprehension, mathematics application, mathematics calculation, and spelling (Kaufman, A. S. & Kaufman N. L. 1985).

Reliability of the Kaufman Test of Educational Achievement has a reliability coefficients ranged from .87 to .95 for all ages. Internal consistency demonstrates strong reliability in this area. Coefficients ranged from .77 to .85 by grade level and from .82 to .88 by age group. Intervals in test-retest ranged from 1 to 35 days. In the majority of cases the results demonstrated a .90 or greater on test-retest coefficient (Kaufman & Kaufman, 1985).

Given that there are two forms of the K-TEA (Brief and Comprehensive), reliability between the two were analyzed, in the majority of cases the results demonstrated interform reliability coefficients to be in the low .90s, with a range from .87 to .96 for the various grade levels and .90 to .97 for the different age groups. Interform reliability coefficients for reading were higher (in the .90s) for younger students and dropped into the upper .70s for older students (Kaufman & Kaufman, 1985).

The validity data of the correlate performance on both forms of the K-TEA with other achievement tests are presented in the Kaufman Test of Educational Achievement: Comprehensive Form manual (Kaufman, 1994). Other tests consist of the Wide Range Achievement Test, the Stanford Achievement Test, and the K-ABC the Peabody Individual Achievement Test (PIAT), and the Metropolitan Achievement Test. The creators of the K-TEA put together information to reinforce relatively strong correlations on the majority of these measures (e.g., K-ABC ranged from .83 to .88; PIAT ranged from .75 to .86).

The Kaufman Test of Educational Achievement, Brief Form has been validated with mentally retarded students. To examine the validity of the Kaufman Test of Educational Achievement Brief Form, standard scores were correlated with Woodcock-Johnson Psycho-Educational Test standard scores and WISC-R Verbal, Performance, and Full Scale IQs (Kaufman, A.S. 2001). Kaufman scores were highly related to Woodcock-Johnson scores and moderately related to WISC-R scores. Mean comparisons concerning composite scores were not significant. These results were similar with data reported in the Kaufman test manual and offer positive support for the concurrent validity of this test (Kaufman & Kaufman, 1985).

In conclusion, The Kaufman Test of Educational Achievement is a norm-referenced test individually administered to students in grades 1 through 12, presented on an easel with only one or a small number of items per page. It is focused on the areas of reading decoding, reading comprehension, mathematics application, mathematics computation, and spelling. Its reliability coefficients ranged from .87 to .95 for all ages. There are two overlapping forms: Comprehensive and Brief, they are both norm-referenced and set at a mean of 100, with a standard deviation of 15.
