What Subtests are on the DIBELS Test?
DIBELS, the Dynamic Indicators of Basic Early Literacy Skills test, consists of six subtests or measures that assess specific literacy skills. The specific subtests within DIBELS may vary depending on the version and grade level being used, but here are the subtests you will encounter on the DIBELS – 8th Edition.
Sound/Letter Knowledge –
- LNF or Letter Naming Fluency (K-1st grade): LNF measures a student’s ability to name letters quickly and accurately. Students are presented with a sheet containing random letters and are timed to see how many letters they can name correctly in one minute. (Test time – 1 minute)
Phonemic Awareness –
- PSF or Phonemic Segmentation Fluency (K – 1st grade): PSF assesses a student’s phonemic awareness by asking them to break down spoken words into individual phonemes or sounds. The student is given a word and must say all the individual sounds they hear in that word. (Test time – 1 minute)
Decoding and Reading Fluency –
- NWF or Nonsense Word Fluency (K – 3rd grade): This subtest evaluates a student’s ability to decode unfamiliar or nonsense words. Students are presented with a list of made-up words and are timed while reading them aloud. The number of words read correctly per minute is recorded. (Test time – 1 minute)
- WRF or Word Reading Fluency (K – 3rd grade): WRF measures a student’s ability to read as many words as they can (including high frequency words). (Test time – 1 minute)
- ORF or Oral Reading Fluency (1st – 8th grade): Students are given 1 minute to read out loud as far through a passage as they can. The student is given a percent accuracy score on this subtest. It is one of the strongest measures of evaluating growth over time. (Test time – 1 minute)
- Maze (2nd – 8th grade): In this subtest, students are presented with a passage in which some words are missing. They must choose the correct multiple-choice answer for the missing words. Maze Passage assesses a student’s reading comprehension and contextual word recognition. (Test time – 3 minutes)

How is the DIBELS Scored?
The scoring of DIBELS assessments is anchored in specific criteria for each subtest. These scores serve the pivotal role of pinpointing students facing potential reading challenges, thus guiding instructive decisions. Schools frequently establish benchmarks to appraise whether students meet grade-level expectations.
DIBELS – 8th Edition evaluates students based on five types of scores:
- Raw Scores
- Equated Scaled Scores
- Percentile Ranks
- Growth Zones
- Composite Scores
