The 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.


Updated for Telepractice
Now we have the evidence that this trusted test can be reliably administered using distance technology when you can’t see students face to face! After a timely 2020 study supported the validity of administering TILLS virtually, the TILLS developers now include updated Tele-TILLS materials to guide users who are supporting students in online settings. The Tele-TILLS components are:
  • Digital Tele-TILLS Stimulus Book. This audio-enhanced stimulus book contains the stimuli needed to administer the TILLS subtests virtually.
  • Tele-TILLS instructions. A PDF of clear guidelines for administering TILLS using distance technology, including technical details, materials needed, step-by-step examiner instructions, and tips on scoring and interpreting results.
  • Facilitator instructions. A handy, one-page quick guide for parents and other adult facilitators who are assisting with technology setup and troubleshooting during virtual administration of TILLS.
To deliver the Tele-TILLS, examiners will need paper copies of the Examiner Record Form and the Student Response Form. The Student Response Form should be delivered to the location of the student prior to testing.


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 across the United States.


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.


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)
