Wide Range Achievement Test, Fourth Edition (WRAT-4) - Frequently Asked Questions

What is the difference between the Blue and Green Forms?

The alternate forms (i.e., Blue Form, Green Form) can be used interchangeably with comparable results. They have different items and good retest validity, which allows for retesting within short periods of time without the potential practice effects that may occur from repeating the same items. Each form contains the same items for Part 1 of three subtests, but these items are administered only to young examinees and those who perform poorly on Part 2 items.

 

When should I use the Combined Form?

The alternate forms (i.e., Blue Form, Green Form) can be administered together in a single examination (i.e., Combined Form). This further improves reliability and reduces the confidence interval. Administering both forms also offers more opportunities for qualitative assessment of an examinee's performance on a particular subtest.

 

What norm groups are available?

Grade norms are provided for students Reception to Year 13 by term (Autumn and Spring). Age norms are provided for examinees aged 5 years - 94 years 11 months.

 

What subtests can be administered in a group setting?

For both convenience and efficiency, Part 2 of the Spelling and Maths sComputation subtests can be administered in a small-group setting. Part 1 of each of these subtests must be administered individually, but this is only required for ages 7 or younger. Older examinees typically only need to be administered Part 1 when performance is well below average.

 

What is the Reading Composite?

Reading requires related but distinct skills such as decoding words and understanding how words work together to make meaning.

The Word Reading subtest measures letter and word decoding, while the Sentence Comprehension subtest measures the ability to gain meaning from words and to comprehend ideas.

Standard scores for these subtests are useful on their own, but when the standard scores are combined, they yield a Reading Composite score. This score offers a more comprehensive view of reading performance than either subtest score can provide on its own.
