Readability Analysis

Flesch Reading Ease Algorithm

Scientific approach to content readability assessment:

Calculation Formula

Flesch Score = 206.835 - (1.015 × ASL) - (84.6 × ASW)

Where:
- ASL = Average Sentence Length (words per sentence)
- ASW = Average Syllables per Word

Score Interpretation

90-100: Very Easy (5th grade level)
80-89: Easy (6th grade level)
70-79: Fairly Easy (7th grade level)
60-69: Standard (8th-9th grade level)
50-59: Fairly Difficult (10th-12th grade level)
30-49: Difficult (College level)
0-29: Very Difficult (Graduate level)
