Age Range: 3:0–21:11 (LC/OE); 5:0–21:11 (RC/WE)
Completion Time: LC: 10–20 minutes; OE: 10–30 minutes; RC: 10–30 minutes; WE: 15–30 minutes
Scores/Interpretation: Age- and grade-based standard scores (M = 100, SD = 15), testage equivalents, percentile ranks, and descriptive categories; plus 5 Composites—Oral Language, Written Language, Receptive Processing, Expressive Processing, and Overall Language Processing
Scoring Options: Software or manual scoring
OWLS-II offers an integrated, global approach to language assessment with a new Reading Comprehension Scale, updated norms, new items, a parallel form, improved scoring guidelines, and full-color stimulus materials. A helpful new handbook, Foundations of Language Assessment, makes it easier to understand the test and interpret results.
Users & Applications
Use OWLS-II to:
- Identify students with learning disabilities, language disorders, and related difficulties in accordance with IDEA requirements
- Design targeted interventions that address potential academic difficulties
- Monitor progress, using the new alternate form
- Gather longitudinal data for research purposes
Content & Administration
The four OWLS-II scales, Listening Comprehension, Oral Expression, Reading Comprehension, and Written Expression, give you a complete, accurate, and useful picture of language skills. Each of the four scales assesses four linguistic structures:
Scoring is fast and reliable
The LC easel and the record form contain correct responses for each item for on-the-spot scoring. For the OE, the examiner may do a preliminary tally and then consult the item-by-item scoring rules to determine scores of particular items.
Together, the LC and OE Scales assess receptive and expressive language. Neither scale requires reading on the examinee’s part and both scales feature colorful, updated artwork.
Written language is assessed using the RC and WE scales. The new RC Scale measures the receptive aspects of written language and is uniquely effective in identifying language factors that may be impairing or facilitating reading comprehension. The WE Scale, which measures the expressive aspects of written language, has been significantly improved in the OWLS-II.
Scoring & Reporting
The OWLS-II optional computer scoring program converts raw scores to scale scores, compares scale scores, calculates composites, and generates a graphic score profile. It also provides high-level item analysis and detailed narrative interpretation. This program saves time and gives you an extremely useful summary of test results.
