Assessment measurement videos

mCLASS’s teacher-administered assessment provides for streamlined data collection, emphasizing measures of the most important skills. The measures are administered in the manner that is most appropriate for the developmental stage of the child as well as the skills being assessed. 

Phonemic Segmentation Fluency (PSF)

The student produces sounds to isolate first sounds or fully segments sounds in spoken words.

Word Reading Fluency (WRF)

Standardized, individually administered assessment that provides a measure of Alphabetic Principle and Reading Fluency skills. The student reads individual words aloud from a word list printed on a sheet of paper for one minute.

Oral Reading Fluency (ORF)

Students are tasked with verbally repeating what they hear, and thus teachers have deeper diagnostic data about their oral language abilities and errors.

Nonsense Word Fluency (NWF)

This test assesses students’ skills in decoding one-syllable nonsense words by associating the most common sound with each letter and blending those sounds to decode whole words.

Letter Naming Fluency (LNF)

A standardized, individually administered test that provides a measure of risk. Students are presented with a page of upper- and lower-case letters arranged in a random order and are asked to name as many letters as they can.
