Acadience Reading Pre-K: PELI®

Announcing the official release of Acadience Reading Pre-K: PELI

The authors of the Acadience family of assessments are excited to announce the full release of the Preschool Early Literacy Indicators (PELI). For over 10 years, PELI has undergone extensive research and development resulting in the final set of measures that exist today.

  • PELI Technical Data
  • Alternate-form reliability: .85 to .92
  • Inter-rater reliability: .90 to .98
  • Criterion-related validity (PPVT): .62 to .72
  • Criterion-related validity (Acadience Reading): .66 to .74

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 is 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.

Assessment Materials

PELI materials are available for purchase in Classroom Kits that include everything needed to assess a classroom of up to 20 preschool children. Each 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 assessment books and other materials are also available for individual sale.

Materials may be ordered directly from Acadience Learning using a PELI Order Form. Contact us at for more information.

Training Options

Our annual Acadience Super Institute is an excellent opportunity for receiving PELI training in person. The PELI Essential Workshop and the PELI Data Interpretation/Mentoring Workshop will both be available at the 2019 Acadience Super Institute. Individuals who complete these workshops will become PELI Mentors and receive access to Acadience Learning’s official PELI training materials to use with others. Visit the Acadience Super Institute page for more information.

The PELI Essential Workshop is available as a pre-recorded, online training. The cost is $129.00 per user for a 30-day subscription. Each subscription includes a printed training book containing the slides, activities, and other useful resources. Register at Acadience Online Training.

The PELI Data Interpretation and Mentoring workshop is available semi-annually as a live online webinar. You can find more information about upcoming training opportunities on our Training and Professional Development page.

The PELI Essential and PELI Data Interpretation/Mentoring workshops are also available for live onsite training by request. For more information, please email us at

Data Management

PELI data entry and reporting in Acadience Data Management is free for the 2019-2020 school year while we work on developing additional reports and features for the assessment. To set up an Acadience Data Management account, visit our sign up page.

Acadience Data Management automatically calculates the PELI Composite Score and PELI Language Index and equates the scores for you. Sites that choose not to enter PELI scores in Acadience Data Management will need to use formulas and tables (included in the Assessment Manual) or data entry spreadsheets (provided upon request) to ensure that scores are properly calculated and equated. Email us at for more information.

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 Acadience™ Reading K–6 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 Acadience Reading Kindergarten beginning-of-year benchmark goal as the criterion are .77 and .88 respectively (CA = .77; AUC = .87)
