# STUDENT LANGUAGE SCALE

## SCREENER for Language & Literacy Disorders

### What is it?
The Student Language Scale (SLS) reliably screens students ages 6–18 years for language/literacy disorders, including dyslexia. Filled out by parents, teachers, and students, the screener is a quick, cost-effective way to see how students are performing on academic tasks as compared to their same-age peers.

### What are the purposes of the SLS?
- Screen for language/literacy disorders, including dyslexia, by gathering teachers’ and parents’ ratings of students
- Gather input about a struggling student’s strengths and needs from multiple sources
- Enhance home–school communication by gaining new insight into the student’s performance and the teachers‘, parents’, and student’s perspectives on it, whether or not everyone agrees and whether or not there are concerns
