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 2018-2019 school year. PELI data collected during the 2018-2019 academic year will be used to update current percentile ranks for PELI from a nationally representative sample of schools/programs.

  • 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. Ten alternate PELI books are designed around common preschool themes. 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 PELI assessment 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. PELI Quick Checks are available for more frequent progress monitoring 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 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 from Dynamic Measurement Group. 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 2018-2019. Visit the DIBELSnet sign up page for more information on setting up an account. Basic reports for the PELI are available at the classroom, school, and district level.


How to Use the PELI Early Release for 2018-2019


New Participants

To get started, email us at info@dibels.org 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 2017-2018 and you wish to continue participating in 2018-2019, please email us at info@dibels.org 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, 2018.

We look forward to working with you during the 2018-2019 school year.


Training Information

The new online PELI Essential Workshop is $129.00 per user for a 30-day subscription. Each online training subscription includes a training book containing the slides, activities, and other useful resources. To register for the online training, please email us at info@dibels.org.

The PELI Data Interpretation and Mentoring workshop is available as a live online webinar or in-person training event. You can find the current list of upcoming training events on our Training and Professional Development page. Both the PELI Essential and PELI Data Interpretation and Mentoring 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 info@dibels.org.


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 info@dibels.org.

Assessment materials are bundled by age group (Pre-K Ages 3-4 and Pre-K Ages 4-5). PK 3/4 books are to be administered to those children who are two years away from kindergarten entry at the beginning of the 2018-2019 school year. PK 4/5 books are to be used with children who are one year from kindergarten entry at the beginning of the 2018-2019 school year, that is, children who will be eligible for kindergarten entry in 2019. If your program serves both age groups and you will be assessing all children, you will need both PK 3/4 and PK 4/5 books.

Each PK 3/4 and PK 4/5 Classroom Kit contains 5 assessments books (3 benchmark and 2 interim progress monitoring forms), 20 score forms per benchmark book, 10 score forms per interim book, the PELI Assessment Manual, and PELI Quick Check materials. Quick Check materials include child-facing materials and 5 scoring booklets each for Alphabet Knowledge, Vocabulary-Oral Language, and Phonological Awareness. The cost per Classroom Kit is $125.00. 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 Composite Score ranges from .85 to .92.
  • Alternate form reliability of the PELI subtests ranges from .66 to .95
  • Inter-rater reliability of the PELI ranges from .90 to .98.
  • Concurrent criterion-related validity of language subtests and the PELI Language Index with the Peabody Picture Vocabulary Test ranges from .62 to .72.
  • Concurrent criterion-related validity of Alphabet Knowledge and Phonological Awareness subtests with the DIBELS Next Composite Score (beginning of kindergarten measures administered at the end of Pre-K) ranges from .66 to .74.
  • Sensitivity and specificity of the PELI Composite Score end-of-year benchmark goal with the Peabody Picture Vocabulary Test as the criterion measure = .61 and .81 respectively
    (CA = .74; AUC = .81).
  • Sensitivity and specificity of the PELI Composite Score end-of-year benchmark goal with the DIBELS Next Kindergarten beginning-of-year benchmark goal as the criterion are .77 and .88 respectively (CA = .77; AUC = .87)
