One of the hardest parts of teaching phonics at home is not knowing whether it is actually working. Your child does the lessons, practices the sounds, reads the decodable books. But is it sinking in? How can you tell?

Here is what to look for, what to worry about, and what to adjust.

Signs Phonics Is Working

These are the green lights that tell you things are moving in the right direction:

They sound out unfamiliar words. This is the biggest one. When your child encounters a word they have never seen before and their first instinct is to look at the letters and work through the sounds, phonics is doing its job. Even if they are slow. Even if they need a second try. The instinct to decode is what matters.

They self-correct. Your child reads "hat" as "hot," pauses, looks again, and says, "Wait, hat." That self-correction means they are monitoring their own reading. They noticed something did not match and went back to check. This is a huge skill.

They notice patterns. "Mom, cat and bat rhyme! They both have -at!" When your child starts seeing patterns in words without you pointing them out, their phonics knowledge is becoming automatic.

They can read new decodable texts. If your child can pick up a decodable book at their level and read it with reasonable accuracy on the first try, the skills are transferring. They are not just memorizing specific books; they are applying what they know.

They can spell simple words. Reading and spelling are two sides of the same coin. If your child can hear a CVC word and write the correct letters, that tells you their sound-letter connections are solid.

Signs It Might Not Be Working

They memorize instead of decode. If your child can "read" books they have heard many times but struggles with new text, they may be relying on memory rather than phonics skills. Test this by writing a simple sentence with words they should be able to decode and see if they can read it cold.

They guess based on first letters. Seeing "b" and saying "ball" when the word is "big" is a sign they are not working through the full word. They are using partial cues instead of complete decoding.

They have plateaued for more than 3-4 weeks. Progress is not always linear, but if you have been working on the same skill for a month with no improvement, something needs to change. Not your child; your approach.

They avoid reading. A child who consistently resists reading practice may be struggling more than they are letting on. Avoidance is often a signal that the work feels too hard or too frustrating.

They cannot blend. If your child knows individual letter sounds but cannot push them together to form words, blending is the bottleneck. (Check out my guide on teaching blending for help with this.)

Realistic Expectations by Stage

Phonics is not a quick fix. Here is roughly what to expect:

Pre-K to early K: Your child is learning letter sounds and beginning to blend simple CVC words (cat, sit, hop). Some kids get this in weeks; others take months. Both timelines are normal.

Mid to late K: Blending should be getting smoother. Your child should be able to read simple decodable sentences. They are starting to recognize some common sight words.

First grade: CVC words should be fairly automatic. Your child is working on blends (frog, stop), digraphs (ship, chat), and silent-e words (cake, home). Reading is getting smoother but still takes effort.

Second grade: Most common phonics patterns should be in place. Your child is tackling longer words, vowel teams (rain, boat), and multi-syllable words. Reading starts to feel more natural.

Third grade and beyond: Phonics knowledge should be mostly automatic. Your child is reading for meaning and handling complex text. If basic decoding is still a struggle at this point, consider getting an evaluation.

What to Adjust

If things are not clicking, here are the most common fixes:

Slow down. You might be moving through skills too quickly. Go back to the last point where your child was confident and rebuild from there.

Add more practice. Some kids need 50 repetitions; some need 500. Neither number is wrong. Use decodable books, flashcards, word building activities, and games to get more practice without more worksheets.

Change the approach. If your current program is not resonating, try a different one. Some kids learn better with tiles they can touch, some with writing, some with songs and movement. There is no single right way.

Check for gaps. Sometimes a child struggles with blends because their individual letter sounds are not solid. Go back and check the foundation before building higher.

Get help if needed. If your child is working hard, you are being consistent, and progress is still stalled after several months, consider having them evaluated for a learning difference like dyslexia. Early identification makes a real difference.

Trust Yourself

You do not need a teaching degree to teach phonics well. You need a systematic approach, patience, and the willingness to adjust when something is not working. The fact that you are paying attention to whether it is working means you are already doing this well.
