How Many Letters and Letter Sounds Should Young Children Know, And By When?


No More Teaching A Letter A Week is the latest offering in the Not This But That series, edited by Ellin Keene and Nell Duke. In this new book, early literacy researcher Dr. William Teale argues that alphabet knowledge is more than letter recognition, and he identifies research-based principles of effective alphabet instruction. Literacy coach Rebecca McKay brings those principles to life through purposeful practices that invite children to create an identity through print.

In today's post adapted from the book, William Teale introduces how children learn the alphabet, and how phonics standards differ across the country.

How Many Letters and Letter Sounds Should Young Children Know, And By When?

by William Teale

This question becomes important in light of the differing standards for alphabet knowledge that can be found for preschoolers:

  • Alaska, Alabama, Arizona, South Dakota—at least 10 letters
  • Indiana—13 uppercase letters
  • The Head Start Outcomes Framework—“Identifies at least 10 letters of the alphabet, especially those in their own name”
  • Early Reading First Performance Targets—16 to 19 letters.

You get the picture—standards for alphabet knowledge vary considerably. What does research say about what standards should be? There is as yet no comprehensive answer to this question, in part because the question itself is multifaceted: Is it how many to be considered not at risk? To be successful in reading at third grade? At first grade? And so forth… It is also the case that few studies have addressed this question directly. The best indicator we have to date comes from research conducted by Piasta, Petscher, and Justice (2012). They investigated the diagnostic efficiency of various upper- and lowercase letter-naming standards for 371 preschoolers, and one particular question in the study attempted to identify “optimal benchmarks.” Findings indicated that an end-of-preschool/beginning of kindergarten benchmark of ten letters was adequate to determine negative predictive power (the vast majority of children reaching this benchmark would not be at risk for low literacy achievement in grade 1), but also that optimal benchmarks were eighteen uppercase letters and fifteen lowercase letters when considering the three later grade literacy outcomes of letter–word identification, spelling, and passage comprehension. Thus, Piasta, Petscher, and Justice (2012) advocate setting higher end-of-preschool benchmarks than those typically appearing in state early learning standards or Head Start standards.

Overall conclusions based on research about how young children learn the alphabet are outlined in the figure below.

    I am finding this research particularly interesting. I teach four year old kindergarten in a public school setting. Our end of the year goal is for our students to know at least 50 uppercase and lowercase letters and at least 20 out of 26 letter sounds. I am worried that this goal is not developmentally appropriate for many of my students.I agree that a goal higher than 10 or 12 letters is developmentally appropriate, but I think a goal of 50 is a bit excessive. Our district stresses data and ,as a result, the other preschool teachers and I find that we are teaching letters and sounds to the detriment of other vital preschool skills like social-emotional development.
