I am considering having him repeat fifth grade. He may need another year developmentally, and a review of the material can only help. Certainly, I can't send him to sixth grade without asking for trouble. Please advise.
You should request now that your son be placed on his school's list for assessment testing to determine why he is having problems. If the school won't be able to test your child promptly when school resumes, you may want to investigate testing by a private counselor.
We realize that three teachers have said that your son does not have a learning disability. They well may be right, as most children with learning disabilities are identified by third grade. Some, however, are not identified until the upper-elementary grades or even high school, because a problem does not become evident until the demands of school exceed the child's skill in coping with his or her disability. Also, we want you to be aware of the fact that gifted children can be learning disabled.
Regardless of the assessment results, your son will still need help this year in handling his schoolwork. The school may be able to provide this help. If not, you may need to find it through a tutor or learning center.
In the meantime, be sure to remind your son of the solid strengths that he has demonstrated in reading, word usage, and grammar. These are very important skills that all children need to succeed in school and can be used to improve his weaknesses.
