It works for pupils aged between 11 and 14 but with reading ages of seven to 10.
I use this rule-of-thumb method: take a 100-word sample from a book. Each word has at least one syllable. Count the number of syllables over that.
For example, 100 basic syllables plus 20 extra syllables scores 20. Repeat with another 100-word sample. Average the two results: 20 over 100 and 28 over 100 scores 24. One more sample might be needed if your results are widely different. Match the score with this table:
* Syllable score 15-20, reading age seven, colour-code black
* Syllable score 20-30, reading age eight, colour-code blue
* Syllable score 30-40, reading age nine, colour-code red
* Syllable score 40 - 50, reading age 10 years, colour-code green
