Summary of the Four Major Scores:

• Word Reading Comfort Level:

The level at which the student knows almost all of the words and can read each without any assistance.

• Word Reading Instructional Level

The level at which the student knows 85% to 90% of the words and reads easily enough to gradually acquire the new vocabulary and associated skills.

• Word Reading Frustration Level

The level at which the student is unable to read so many words and therefore misses the essence of passage and finds the task of reading uncomfortable or unpleasant.

• Comprehension of Passage Levels

The level at which the student is able to understand and remember the facts and subtleties of passages (Both Reading and Listening Comprehension and tested).

More Info:

An initial pool of 3,221 reading words were obtained by having 71 teachers, Grades 1 through 12, submit lists of up to 100 words typically taught for the first time at their grade level. Seven years of word-sample use helped verify the 84-word range content of the DSTR, yielding four major scores.

Percentile ranks, T-scores, and grade equivalent scores are available for each form (Form A and Form B) and for the two forms combined (Form 1 + Form B). These scores are also presented for the phonics and sight subtests for each form. Since the sample of 95 students, each in Grades 2 through 8 (average level reading comprehends), scored essentially identical in reading and listening comprehension, the same norms are used for both (r = .94). Reliability and validity are both quite high for such a short, wide ranging power test.
