Is it a reading disorder or developmental lag?

Get expert advice on identifying and addressing reading problems in your child's early years.

By Susan Hall, Ed.D.

How do parents know if their child's reading delay is a real problem or simply a "developmental lag?" How long should parents wait before seeking help if their child is struggling with reading? In this article, Susan Hall, Ed.D., answers these questions.

As I travel across the country speaking to groups of parents about reading difficulties, I often say "beware of the developmental lag excuse." I have several reasons for saying this. First, I have listened to parent after parent tell me about feeling there was a problem early on, yet being persuaded to discount their intuition and wait to seek help for their child. Later, when they learned time was of the essence in developing reading skills, the parents regretted the lost months or years. Second, research shows that the crucial window of opportunity to deliver help is during the first couple of years of school. So if your child is having trouble learning to read, the best approach is to take immediate action.

Knowing how soon to act can be easy if you are informed about important conclusions from recent research. Reading researchers tell us the ideal window of opportunity for addressing reading difficulties is during kindergarten and first grade. The National Institutes of Health state that 95 percent of poor readers can be brought up to grade level if they receive effective help early. While it is still possible to help an older child with reading, those beyond third grade require much more intensive help. The longer you wait to get help for a child with reading difficulties, the harder it will be for the child to catch up.

The three key research conclusions that support seeking help early are:

  • 90 percent of children with reading difficulties will achieve grade level in reading if they receive help by the first grade.
  • 75 percent of children whose help is delayed to age nine or later continue to struggle throughout their school careers.
  • If help is given in fourth grade, rather than in late kindergarten, it takes four times as long to improve the same skills by the same amount.

Parents who understand these research conclusions realize they cannot afford to waste valuable time trying to figure out if there really is a problem or waiting for the problem to cure itself.

These research conclusions make it imperative for schools to implement screening tools that emphasize phonemic awareness skills. As discussed in the earlier Q & A on Assessment Issues, the best plan is to begin screening children in mid-kindergarten and continue screening at least three times a year until the end of second grade.

Reading researchers who designed these screening tools recommend identifying and providing additional assistance to the lowest 20 percent of children. The rationale is that it is better to slightly over-identify the number of children who may be "at risk" of reading difficulty than to miss some who may need help. The worst outcome of over-identification is that a child who would eventually have caught on receives some additional help. Parents should follow this strategy and act early because the worst that can happen is their child will get a little extra help she really didn't need.

Yet identification is only the beginning. Effective and intense intervention must be offered immediately. Students who lag behind their peers must be given extra help, preferably in groups of three or fewer students, by a well-trained educator who knows how to deliver effective instruction. Assignment to these groups can be fluid, with children joining whenever the teacher determines skills are lagging and others moving out as they master skills.

Comments from readers

"I'm going to have to agree with this research. My son is now 14 and and still struggles. I had a hunch when he was in 2nd grade, had him tested and told he was just in a class with accelerated learners so he didn't look as smart. In 5th grade, we paid for an intensive vision therapy. We hope to get him through high school. "

"I have known about my son's delayed ability to retain or comprehend information including read, and I know that he needs help, but what are the resources for help? Do you have support information that I can reference? He has had intervention in 1st grade, Continuing SST currently home tutoring and so on. Should I try Kumon? Hooked on Phonics? I feel lost and I'm desperate. "
"Well as answer to your question I have that problem. I am in middle school and I don't have a learning problem but my homeroom teacher who is my math teacher doesn't answer questions. If you asks she yells at you and says why don't you understand? How can you be in gt and not know? She says she 'just taught that' She goes through the lesson way too quickly and then doesn't answer questions. She either yells or points you in the direction of a student who understands. so reguarding your question I would take your child out of that class or even out of the school."
"Last year my child was in kindergarten. The teacher recommended she repeat, I opted not to. She attended a learning center last year and has continued since. She is now in first grade. Her first week of school has had it's ups and downs. She has complained that when she ask for help on writing her teacher says, 'whatever you think it sounds like just write it down'. She is getting discouraged and if I know my daughter, she'll start telling me that she doesn't want to go to school because she's sick and it's only been one full week of school. Now when I use to go to school (believe me it's been many years) the teacher would sit and help me. Have things changed in the schooling system? Is this learning facility even worth sending my daughter to?"
