This concise manual presents the powerful research and technical data behind the Test of Integrated Language and Literacy Skills™ (TILLS™). Professionals will find clear answers to frequently asked questions about the technical data as they learn the specifics of TILLS development and field testing and the composition of the normative sample.

Full chapters are devoted to the validity of TILLS, the reliability of TILLS, and the evaluation and reduction of test bias. Readers will get valuable information on

test development using item response theory (IRT) procedures
measurements of validity for each of the three purposes of TILLS
evidence of additional aspects of construct validity, including confirmation that TILLS scores reflect age-related change and measure skills at both the sound/word and sentence/discourse levels
the documenting of patterns of relative strengths and weaknesses and tracking change over time
TILLS sensitivity and specificity levels, broken down into 9 age bands meaningful to the development of language and literacy skills
strong reliability evidence for intra-class stability, inter-scorer reliability, and test-retest reliability
the assessment process to remove or minimize item-level bias and subtest-level bias
when to adjust cut scores for identifying language and literacy disorders

With this comprehensive resource on the unparalleled research behind TILLS, professionals will be confident that their language and literacy assessments will be completed with an extensively tested, psychometrically sound tool.

Test of Integrated Language and Literacy Skills (TILLS) <show description>

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.

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:

Administer all 15 TILLS subtests.
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.
Complete the Identification Chart to determine if the student has a disorder.
Complete the Profile Chart for an at-a-glance, big-picture look at the student’s current language and literacy skills.
