The typical signs of dyslexia or a reading disorder, often can manifest as early as when a child is learning the alphabet. However, it is more easily detected when a child is in the Third Grade because the expectations for reading are increased. Things that I would look for in an evaluation of a child for a reading disorder is, what's their rate of reading, are they reading at grade level, what's their reading comprehension, and what's their reading vocabulary. The difficulty with memorizing or recognizing letters, letter reversal, difficulty pairing the letter sound with the symbol. Other areas would be that they can read the words, but they don't understand what they are reading. They may not have a reading vocabulary that is as developed as we expected. Their rate of reading may be very, very slow; which impacts reading because it takes so long to get through the passage, it's hard to recall the information that you first read.
