Pragmatic Language Observation Scale (PLOS)

The Pragmatic Language Observation Scale (PLOS; Newcomer, & Hammill, 2009) is a norm-referenced checklist that is completed by teachers or other professionals.


The PLOS is designed for use with individuals ages 8 through 17 years, 11 months. The purposes of the PLOS include: augmenting a comprehensive spoken language assessment; planning and monitoring interventions; and assisting in the referral process. It consists of items related to spoken language behaviors that occur in instructional settings. Items are rated on a 5-point Likert scale.
