For participants age 18 or older, the recommended readability level is grade 10 or below on the Flesch-Kincaid or Consensus scales.
This readability score is intended for the general adult population and seeks to maximize accessibility and comprehension across varying levels of education and literacy. In specific circumstances, the NCU IRB will accept higher readability scores given an appropriate justification based on the education level of the participants or other factors. In addition, the NCU IRB may require lower readability scores for similar reasons.
**The IRB members check in general if the readability level is commensurate with the reading level of the participants. Teachers or leaders in business may have a higher reading level and that is appropriate.
For participants under the age of 18, the recommended readability level, on the Flesch-Kincaid or consensus scales, is 3 grades below the age of the youngest participant.
