Perfect for diagnosing dyslexia and other language/literacy disorders.

Test of Integrated Language & Literacy Skills (TILLS) is the reliable, valid assessment professionals need to test oral and written language skills in students ages 6 - 18 years. TILLS is a comprehensive, norm-referenced test that has been standardized for three purposes:
  • To identify language/literacy disorders
  • To document patterns of relative strengths and weaknesses
  • To track changes in language and literacy skills over time
To achieve these purposes, TILLS is constructed to allow you to derive scores for identifying, tracking, and profiling a student’s strengths and weaknesses and interpreting the results to support decisions about what to do next.
15 Extensively Researched Subtests
The TILLS assessment is all professionals need to capture the complete picture of students’ oral and written language skills. TILLS is composed of 15 subtests that allow examiners to assess and compare students’ language-literacy skills at both the sound/word level and the sentence/discourse level across the four oral and written modalities—listening, speaking, reading, and writing.
Curriculum Relevant
TILLS measures integrated language-literacy abilities that reflect the complex language and literacy demands of the general education curriculum.
Backed By Unparalleled Data
Each TILLS subtest has been fine-tuned to meet strong psychometric standards using scientific evidence gathered in numerous pilot studies and field trials, a national beta trial, and a standardization study with more than 1200 children and adolescents.
Strong Specificity and Sensitivity
TILLS tested both sensitivity and specificity across the full age range covered by the test. In the manual, diagnostic accuracy data are broken down into nine different “age bands” meaningful to the development of language and literacy skills. Sensitivity ranges from 81% to 97%, and specificity ranges from 81% to 100%.
Streamlined Assessment
Professionals can administer the entire test, single subtests, or combinations of subtests in one or more sessions. Comprehensive assessment can typically be administered in 90 minutes or less.
The TILLS Easy-Score is a free, convenient, and responsive web-based application.  The TILLS Easy-Score electronic scoring solution automates the steps of the Scoring Chart and Identification Chart on the Examiner Record Form.
Useful for a Wide Range of Students
TILLS is ideal for evaluating students:
  • suspected of having a primary language impairment, also called specific language impairment
  • suspected of having a learning disability, reading disability, or dyslexia
  • known to have an existing condition associated with difficulties in spoken and written language (such as deaf or hard of hearing, autism spectrum disorder, or intellectual disability)
  • struggling with language and literacy comprehension and social communication skills (such as social communication disorder)
Here’s how to use the TILLS Examiner’s Kit to screen for and diagnose language and literacy disorders, including dyslexia:
First, you’ll identify at-risk students with the evidence based Student Language Scale (SLS), a quick and easy one-page, 12-question screener filled out by the teacher, parent, and student. Complete in less than five minutes, the SLS helps you:
  • Screen for language/literacy disorders by gathering teachers’ and parents’ ratings of students.
  • Gather input about a struggling student’s strengths and needs from multiple sources—a key requirement of IDEA.
  • Enhance home–school communication by gaining new insight into student performance, whether or not there are concerns.
After the SLS helps you identify children at risk for a language/literacy disorder, use TILLS for diagnosis. Here’s how:
  1. Administer all 15 TILLS subtests.
  2. Complete the first page of the Examiner’s Record Form, a chart that helps you score the subtests, compare the scores to those of the student’s same-age peers, and compare the sound/ word composite score to the sentence discourse composite score.
  3. Complete the Identification Chart to determine if the student has a disorder.
  4. Complete the Profile Chart for an at-a-glance, big-picture look at the student’s current language and literacy skills.
