Number Identification Fluency (NIF)

Number Identification Fluency

Number Identification Fluency (NIF) is a standardized, individually administered measure of early numeracy that assesses a student’s ability to orally identify the numerals 1 through 99. Number recognition is essential for later math skills.

To administer NIF, the assessor presents a student sheet of numbers that ranges from 1–99 and asks the student to orally name each number. Since NIF assesses a student’s fluency in identifying numbers, the measure is timed.

Scoring Rules for NIF

  1. Leave correct items blank. Score the student’s response as correct by leaving the item blank if the student correctly names the number.
  2. Slash incorrect items. Score the student’s response as incorrect by drawing a slash (/) through the item if the student states any number other than the correct answer, skips an item or hesitates with an answer after 3 seconds.
  3. Self-corrections. If the student self-corrects within 3 seconds, write “sc” over the item that had been previously slashed. Count that item as correct.
