As a teacher, I focus a lot on Special education
I am grateful for people like you! what does special education mean ?
It is the part of education that focuses on students with various exceptionalities
Oh I see,special education also has to adhere to federal regulations
yes, it is a part of education that separate from state requirements
Surprisingly , Special education programs are fairly new, the US passed a law 1975 for children with disabilities
My main focus as a teacher is teaching ESOL students - students who speak English as a Second Language
What is the business model for teaching ESOL students?
It is not a business, they're taught in public school 
Actually, the term business  model can be used for a variety of fields and processes including education
