I found this in my reading today from Overcoming Dyslexia by Sally Shaywitz, M.D.:
"A child with dyslexia needs a champion, someone who will be his support and his unflinching advocate; his cheerleader when things are not going well; his friend and confidant when others tease and shame him; his advocate who by actions and comments will express optimism for his future. Perhaps most important, the struggling reader needs someone who will not only believe in him but will translate that belief into positive action by understanding the nature of his reading problem and then actively and relentlessly working to ensure that he receives the reading help and other support he needs."
This represents the model all reading tutors should aspire to be for their students.
