For the standardization version of the ARIK-A, the author team selected a total of 130, fouroption
multiple-choice items, 65 for each form (A and B). Reliability indices for the scales and
composite ranged from 0.54 to 0.90. Based on the original item selection criteria and item
analyses data from the 65-item standardization version, the author team created five scales
ultimately, each with 14 items: Alphabetics, Fluency, Vocabulary, Comprehension, and Assessment. Of note, the assessment scale “overlaps” with the four original scales, i.e., there are
three assessment items embedded in each scale focusing on the assessment of reading content
specifically related to that area of reading, e.g., how to assess reading fluency. Two additional
general assessment items were added to the instrument making each scale total 14 items for a
total of 58 items. Additional global scores can be created, following simple view of reading by
Hoover and Gough (1990) (i.e., reading consists of two major components, decoding and
comprehension). Alphabetics and Fluency items can be combined to produce a larger Basic
Reading Skills Global scale; similarly, Vocabulary and Comprehension items may be summed
to form an Advanced Reading Skills Global scale.
