Welcome!
Are you in the USA? If so, then the information at
wrightslaw would apply, and you could also check your
State Laws on gifted education.
The information at
Understood.org, and information about helpful accommodations may both be of interest. Even outside of an IEP/504 providing
accommodations for learning differences or learning disabilities, it is possible that you may be able to present ideas to your school which they may agree to utilize to help further your child's education.
Your child has many more years ahead to benefit from an appropriately challenging curriculum, and to benefit from accommodations which may teach him how to compensate for dyslexia... therefore I *would* recommend outside testing, if there is any chance that it may be utilized to:
- help him understand himself better (strengths, weaknesses)
- help get him a better "fit" in his educational placement and pacing.
Before scheduling testing, proactively familiarizing yourself with the information contained in the links in this
old post may be helpful.
While it is far from an ideal solution, many families help their child by providing "enrichment" outside of the school day: kids get to explore areas of interest, and parents help locate materials, resources, classes, etc to support their child's interests and goals. These extracurricular activities and hobbies allow a child to experience internal locus of control, and the
growth which occurs through appropriate challenge.
