PELI (Pre-K) Early Release

Announcing the Continued Availability of PELI

Dynamic Measurement Group is pleased to announce that it will continue to offer an early release version of the PELI® (Preschool Early Literacy Indicators) for the 2017-2018 school year. PELI data collected during the 2017-2018 academic year will continue to be used to examine the functioning of the current PELI benchmark goals and cut points for risk with a broader sample of students from across the United States and Canada.

  • PELI Technical Data
  • Alternate-form reliability: .86 to .91
  • Inter-rater reliability: .90 to .98
  • Criterion-related validity (PPVT): .70 to .80
  • Criterion-related validity (DIBELS Next): .61 to .67

The PELI assessment is designed for preschool and pre-kindergarten children (ages 3 to 5) and assesses alphabet knowledge, vocabulary and oral language, phonological awareness, and comprehension. The assessment is given in a storybook format that will be familiar to most preschoolers. Each alternate PELI book is designed around a central theme. Book titles include On the Farm, A Day at the Beach, Grandma's Birthday, A Trip to Outer Space, Time for Bed, and others. The measure is untimed and takes about 15 minutes to administer per child.

The PELI assessment is designed to identify children who may be experiencing difficulties acquiring early literacy skills and to inform instructional support for those children in order to improve future reading outcomes. Benchmark assessment books should be administered to all children in a program three times per year (beginning of year, middle of year, and end of year). Interim books are available to assess children between benchmark assessment periods as needed. Experimental progress monitoring materials called PELI Quick Checks are also available. Quick Checks can be given more frequently to monitor the progress of children receiving supplemental literacy support in individual skill areas.

For a printer-friendly overview of the PELI with sample materials, download our PELI Fact Sheet. You can also view our PELI Overview 2015 slides for an overview of the PELI, which show sample pages from the PELI books.

Sites interested in using the PELI will need to purchase materials. In addition, anyone planning on administering the PELI must complete PELI training (more information regarding materials and training is below). Participating sites also must enter their PELI data into DMG's DIBELSnet data reporting service. PELI data entry and reporting will be free for 2017-2018. To sign up for DIBELSnet, visit and click on the purple "Sign Up" button in the lower right-hand corner. Basic reports for the PELI are available at the classroom, school, and district level.

How to Use the PELI Early Release for 2017-2018

New Participants

To get started, email us at with the following:

  1. The name of your school/district and the state in which you are located.
  2. The name and email address of the contact person in your agency who will receive communications about PELI.
  3. The dates for the beginning and end of your school calendar.
  4. Your approximate benchmark testing dates for beginning of year, middle of year, and end of year (e.g., September, January, May).

Once we receive your information, we will send you instructions for completing the remaining requirements (ordering materials, completing training, and accessing DIBELSnet).

Continuing Participants

If your school or district participated in the PELI Early Release in 2016-2017 and you wish to continue participating in 2017-2018, please email us at with the following:

  1. The dates for the beginning and end of your school calendar
  2. Your approximate benchmark testing dates for beginning of year, middle of year, and end of year (e.g., September, January, May).

This information is required in order to set up your DIBELSnet account for PELI data entry and reports. Once we have this information on file, you will automatically receive an email with the new download link on or before August 15, 2017.

We look forward to working with you during the 2017-2018 school year.

Training Information

Online PELI Essential training is available and costs $25.00 per person for 30 days of access. If you would like to register for the online training, please email us at

A more in-depth PELI Essential Workshop, as well as the PELI Data Interpretation and Mentoring Workshop, will be available at the DIBELS Super Institute in July of 2018. Both workshops are also available for onsite training by request. Those who complete both the PELI Essential Workshop and Data Interpretation and Mentoring Workshop will be given PELI Mentor status and receive access to DMG's official PELI training materials that can be used to train others. For more information, please email us at

Materials Information

PELI assessment materials can be ordered directly from DMG by completing a PELI Order Form. To request an order form, please email us at

Assessment materials are bundled by age group (Pre-K Ages 3-4 and Pre-K Ages 4-5). Pre-K 3-4 books are to be administered to those children who are two years away from kindergarten entry at the beginning of the 2017-2018 school year. Pre-K 4-5 books are to be used with children who are one year from kindergarten entry at the beginning of the 2017-2018 school year, that is, children who will be eligible for kindergarten entry in 2018. If your program serves both age groups and you will be assessing all children, you will need both Pre-K 3-4 and Pre-K 4-5 books.

Each Pre-K 3-4 and Pre-K 4-5 bundle contains 5 assessments books (3 benchmark and 2 interim forms), 20 score forms per book, and the PELI Assessment Manual. The cost per bundle is $99.00. We accept purchase orders, credit card payments, and checks.

Technical Adequacy of the PELI

The reliability, validity, and decision utility of the PELI have been investigated in a series of studies from 2009 to the present. The following is a brief summary of results from the most recent studies, including 6079 students across 28 states representing all census regions of the United States. Children with disabilities and children who were English language learners were included in the research provided they had the response capabilities to participate. Unless otherwise indicated, the summary statistics below represent the PELI Composite Score at the end of year.

  • Alternate form reliability of the PELI ranges from .86 to .91.
  • Inter-rater reliability of the PELI ranges from .90 to .98.
  • Criterion-related validity with the Peabody Picture Vocabulary Test raw score
    ranges from .70 to .80.
  • Criterion-related validity with DIBELS Next Composite Score (beginning of
    kindergarten measures administered at the end of Pre-K) ranges from .61 to .67.
  • Sensitivity and specificity of the end-of-year benchmark goal with the
    PPVT = .57 and .90 respectively (AUC = .80).
