Ballotpedia's readability report analyzes what level of education voters would need to understand the ballot titles and summaries of statewide ballot measures using Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL). A readability score is an estimation of the reading difficulty of a text. Measurements used in calculating readability scores include the number of syllables, words, and sentences in a text. Other factors, such as the complexity of an idea in a text, are not reflected in readability scores.
As of February 16, 2026, 66 statewide ballot measures were certified for the ballot in 32 states for elections in 2026.
Readability index details
Ballotpedia uses two formulas, the Flesch Reading Ease (FRE) and Flesch-Kincaid Grade Level (FKGL), to compute scores for the titles and summaries of ballot measures. The FRE formula produces a score between a negative (-) number and 100, with the highest score (100) representing a 5th-grade equivalent reading level and scores at or below zero representing college graduate-equivalent reading level. Therefore, the higher the score, the easier the text is to read. The FKGL formula produces a score equivalent to the estimated number of years of U.S. education required to understand a text. A score of five estimates that a U.S. 5th grade student would be able to read and comprehend a text, while a score of 20 estimates that a person with 20 years of U.S. formal education would be able to read and comprehend a text. Ballotpedia uses Readable.com to calculate the scores.

2026 readability scores
The readability scores will be posted below when ballots are finalized for 2026 elections.
Educational attainment in the U.S.
In 2022, the U.S. Census Bureau reported on the highest level of education of the population age 25 and older in the United States. Of that population, 14% completed advanced education such as a master’s degree, professional degree, or doctorate. The chart below shows the breakdown by highest level of education.[1]
Formulas
The Flesch Reading Ease and Flesch-Kincaid Grade Level formulas use the same variables and are inversely correlated, meaning that as one increases the other decreases.
Flesch Reading Ease
In the 1940s, Rudolf Flesch developed the Flesch Reading Ease (FRE) test. The U.S. Department of Defense uses the FRE to help craft its documents and manuals.[2] The FRE computes a score based on the number of syllables, the number of words, and the number of sentences in a text. The FRE formula is as follows:[3]
The FRE formula was designed to produce a score between 0 and 100, with the highest score (100) representing a 5th-grade equivalent reading level and the lowest score (0) representing college graduate-equivalent reading level. However, a score can be negative, representing increased difficulty. Therefore, the higher the score, the easier the text is to read. Rudolf Flesch created the following guide to interpreting FRE scores:[3]
| Score | School level |
|---|---|
| 90 to 100 | 5th grade |
| 80 to 90 | 6th grade |
| 70 to 80 | 7th grade |
| 60 to 70 | 8th and 9th grade |
| 50 to 60 | 10th to 12th grade |
| 30 to 50 | College |
| 0 to 30 | College graduate |
Flesch-Kincaid Grade Level
In 1975, J. Peter Kincaid recalculated FRE to give a score in the form of a U.S. school grade level for use by the U.S. Navy. This new formula became known as the Flesch-Kincaid Grade Level (FKGL) test. Like FRE, the FKGL computes a score based on the number of syllables, the number of words, and the number of sentences in a text. The FKGL formula is as follows:[4]
The FKGL produces a score equivalent to the estimated number of years of education required to understand a text. A score of 9 estimates that a U.S. 9th grade student would be able to read and comprehend a text, while a score of 18 estimates that a person with 18 years of U.S. formal education would be able to read and comprehend a text.[5]
Limitations
As the FRE and FKGL, along with other readability tests, do not measure the difficulty or complexity of the ideas expressed in ballot measure titles and summaries, they may underestimate or overestimate the ability of voters to comprehend a text. Political scientist Shauna Reilly, who utilizes readability indices in her research, noted their limitations, stating:[2]
| “ | There are limitations to the value of these measurements. No mathematical formula can tell us how complex the ideas of the passage are nor whether the content is in a logical order. Further, these mathematical equations exist in a vacuum and cannot explain the context of the passage.[6] | ” |
Prior research
Ballot Question Readability and Roll-off: The Impact of Language Complexity
In 2011, political scientists Shauna Reilly and Sean Richey published an article in Political Research Quarterly on research they conducted to answer the question of whether the difficulty or complexity of ballot measure language correlated with voters skipping voting on a ballot measure. The authors referred to voters casting ballots but skipping a ballot measure as voter roll-off. To measure the difficulty or complexity of ballot measure language, Reilly and Richey calculated Flesch-Kincaid Grade Level scores for 1,211 statewide ballot measures from 1997 to 2007. Reilly and Richey concluded that lower readability scores correlated with higher rates of voter roll-off. In their model accounting for state and year variations, Reilly and Richey only found one variable with a stronger influence on voter roll-off than readability—whether or not a ballot measure was on a primary election ballot compared to a special election ballot.[5]
Reilly and Richey calculated the mean Flesch-Kincaid Grade Level score for each state, except Arkansas, Illinois, and West Virginia, with at least one ballot measure during the 10-year period from 1997 to 2007. The state with the highest mean score was New Mexico, which had a mean FKGL score of 28 years of education. The state with the lowest mean score was Oklahoma, which had a mean FKGL score of nine years of education. The following table is from Reilly and Richey's research and contains the number of ballot measures analyzed in each state, the mean, minimum, and maximum readability score of measures in each state, and the standard deviation of the readability scores for measures in each state:[5][7]
