I've just finished a masters in special education for grades 1-6 and had the opportunity to teach special education classes and it was a great uplifting experience.
It is true that this is a very involved and dedicated career path. But if you really feel passionate about teaching these very special kids, go for it because it is a truly rewarding experience.
You will be helping kids with many hardships and disabilities not only to learn basic academic concepts but also life skills with lots of love and dedication. You will be improving their lives for the better and remember you will have a team with you consisting of teacher assistants, paraprofessionals, counselors, speech therapists, occupational therapists so that the child with special needs gets all the support that he/she needs. Hope this helps, good luck!
