OPUS

Overview

Overview

The Oral Passage Understanding Scale is a new measure of listening (auditory) comprehension. It evaluates a person's ability to listen to passages that are read aloud and recall information about them. This ability is key to success in the classroom, as well as in social and occupational settings. The OPUS also measures memory skills, which are integral to listening comprehension.

  • Can be cohesively used with CASL-2 and OWLS-II
  • Can be used to track improvement over time
  • Can help answer referral questions e.g.. Can a student sufficiently understand and retain information heard in class?
  • Can be used on its own anytime a measure of how well an individual understands orally presented information
  • Also measures memory skills

A versatile instrument, the OPUS can be used by speech-language pathologists and other professionals in a variety of settings, including schools, clinics, hospitals, private practices, and intervention programs. When you need to evaluate response to intervention (RTI), you can use the OPUS to track improvement over time.

The OPUS consists of 17 passages, each with 7 to 10 associated questions. These passages are divided into six Item Sets to allow for a brief administration time of just 10 to 20 minutes. Each Item Set has 5 passages and up to 44 items. Selecting the appropriate Item Set, based on the examinee's age and ability, ensure that developmentally appropriate items are administered.

The OPUS has strong internal consistency and test-retest and interrater reliability, demonstrating the stability and reliability of results over time and across raters. The OPUS's validity is also supported by expected standard score correlations with other measures of oral language, including the CASL-2

Standardization for the OPUS is based on a sample of 1,517 individuals ages 5 to 21 years. The sample is stratified to match recent U.S. Census data for gender, race/ethnicity, parents' education level, and geographic region so you can confidently use the OPUS with a wide range of individuals.
