As English educators, we understand the crucial role that readability plays in student comprehension and engagement. 

When students can easily understand the texts they encounter, they are more likely to develop a love of reading and achieve academic success. 

The Flesch Reading Ease score is a valuable tool that can help us assess and improve the readability of materials we use in our classrooms, leading to more effective learning experiences.

What is the Flesch Reading Ease Score?

The Flesch Reading Ease score is a readability formula that calculates a score between 0 and 100, indicating how easy a piece of text is to understand. The higher the score, the easier the text is to read. 

This score is determined by analysing two key factors:

• Sentence length
• Word complexity (measured by the number of syllables per word). 

Shorter sentences and simpler words result in a higher score, indicating greater readability.

For example, a text with a Flesch Reading Score of 85 would be considered easy to read, characterized by shorter sentences and simpler vocabulary. Such a text, like a basic news article or simple instructions, is accessible to a wide audience. By using the Flesch Reading Ease score, educators can quickly assess text accessibility and make informed decisions regarding their classroom application.

What is a good Flesch Reading Ease Score?

For general audiences, a Flesch Reading Ease score between 60-70 is typically recommended. This range corresponds to a reading level accessible to most secondary school students and adults, making it suitable for a wide variety of content, from web articles to general informational texts. 

Flesch Reading Ease vs. Flesch-Kincaid Grade Level

While both Flesch Reading Ease and Flesch-Kincaid Grade Level assess readability, they differ in their scoring systems and applications. 

The Flesch Reading Ease provides a general score from 0 to 100, while the Flesch-Kincaid Grade Level translates readability into a U.S. school grade level. 

For educators, both scores can be useful, but the Flesch Reading Ease may be more versatile for assessing a wider range of texts, including those beyond traditional educational materials. See the table in the next section for an approximate conversion between the two metrics.

Understanding Flesch Reading Ease Score Ranges

The Flesch Reading Ease score can be interpreted using the following table, which outlines typical score ranges, their corresponding school levels (for comparison), and common uses:

Flesch Reading Ease Score	School Level Equivalence	Approximate UK Equivalence	Typical Usage
90-100	5th grade	Primary School (KS2)	Very easy to read; children’s books, simple instructions.
80-90	6th grade	Lower Secondary (KS3)	Easy to read; comic books, basic fiction.
70-80	7th grade	Lower Secondary (KS3)	Fairly easy; general fiction, popular magazines.
60-70	8th & 9th grade	Lower Secondary (KS3)Upper Secondary (KS4)	Plain English; most web content, newspapers.
50-60	10th-12th grade	Upper Secondary (KS4-5)	More complex; technical writing, academic texts.
30-50	College	University Level	Difficult; specialized articles, legal documents.
0-30	College Graduate	University Level	Very difficult; academic papers, complex technical manuals.

Essentially, this table provides a quick reference for understanding the Flesch Reading Ease score , showing who can easily understand a text at each score and when a text with such a score might be used.

Remember that it’s essential to adjust this range based on the specific audience and purpose, as higher scores may be needed for younger readers or those with lower literacy levels, and lower scores for specialized academic materials.

Understanding the Flesch Reading Ease Formula

While the exact formula for calculating the Flesch Reading Ease score may appear complex, the underlying principles are straightforward. 

The Flesch Reading Ease formula takes into account two main factors:

• Average Sentence Length: Calculated by dividing the total number of words by the total number of sentences.
• Average Syllables per Word: Calculated by dividing the total number of syllables by the total number of words.

These factors are then combined in a specific formula to produce the final Flesch Reading Ease score:

$$ \begin{aligned} \text{Reading Ease} = & 206.835 – \left(1.015 \times \frac{\text{Total Number of Words}}{\text{Total Number of Sentences}}\right) – \left(84.6 \times \frac{\text{Total Number of Syllables}}{\text{Total Number of Words}}\right) \end{aligned} $$

Understanding these components can help educators guide students in writing clearer and more concise sentences, as well as choosing simpler vocabulary when appropriate.

Tools like Text Inspector automate the calculation of the Flesch Reading Ease score, making it easy for educators to assess readability without manual calculations. However, understanding the formula provides valuable insight into how the score is derived and how to improve it.
