Is My Adult Learner Struggling with Decoding or Fluency?
What’s the Difference?
Decoding: Reading the words
Decoding is the ability to use letter-sound patterns and meaningful word parts to figure out unfamiliar words.
A learner may need more decoding support if they:
- Struggle to sound out unfamiliar words
- Guess words based on the first letter
- Frequently substitute or mispronounce words
- Skip or misread prefixes and suffixes
- Have difficulty breaking longer words into smaller parts
- Understand less because words are read incorrectly or skipped
Fluency: Reading the text smoothly
Fluency is the ability to read connected text accurately, smoothly, and with appropriate phrasing and expression.
A learner may need more decoding support if they:
- Struggle to sound out unfamiliar words
- Guess words based on the first letter
- Frequently substitute or mispronounce words
- Skip or misread prefixes and suffixes
- Have difficulty breaking longer words into smaller parts
- Understand less because words are read incorrectly or skipped
What Can I Observe?
During one-on-one or small-group reading, ask:
Can the learner sound out an unfamiliar word?
Difficulty may point to decoding.
Can the learner recognize and read prefixes, suffixes, and parts of longer words?
Difficulty may point to decoding.
Can the learner read individual words correctly but struggles when those words appear in a passage?
This may point to fluency.
Does the learner read in short, meaningful phrases or one word at a time?
Word-by-word reading may point to fluency.
Is reading accurate but unusually slow or lacking expression?
Word-by-word reading may point to fluency.
What’s the Difference?
If decoding seems to be the main challenge:
- Explicitly teach common sound-spelling patterns
- Practice breaking longer words into syllables
- Teach roots, prefixes, and suffixes
- Provide untimed practice with unfamiliar words
- Use meaningful, adult-appropriate words and texts
If fluency seems to be the main challenge:
- Model fluent reading and have learners read the same text after you
- Use short, repeated readings of meaningful passages
- Mark natural phrase breaks in sentences
- Practice paired or choral reading
- Provide immediate, supportive feedback
If both are difficult:
- Strengthen word-reading skills first
- Build automatic recognition of important, frequently used words
- Gradually move from word practice to connected-text reading
- Continue oral reading practice with teacher feedback
Things to keep in mind:
- Familiar words can hide decoding difficulties. An adult may easily recognize words used frequently at work or in daily life while still struggling to decode unfamiliar words.
- Avoid relying only on timed reading. Time pressure may affect performance and may not show what the learner can actually do.
- Prioritize high-impact instruction. Work, family responsibilities, and attendance can limit instructional time, so focus practice on the learner's most important reading needs.
The Bottom Line
- If the learner struggles to figure out the words → focus on decoding.
- If the learner knows the words but struggles to read them smoothly in text → focus on fluency.
- If both are difficult → strengthen decoding while gradually building fluent reading.
