Put very simply, remedial education applies to children who have average to above average intellectual abilities, but do not perform according to their potential as a result of difficulties with reading and/or writing and/or arithmetic.

Whereas special educational facilities cater for children with below average intellectual abilities.

Some schools also advertise that they offer mainstream with assistance.  In these schools children with remedial problems receive extra help and individual attention with mainstream subjects, but remediation of reading and/or writing and/or arithmetic problems do not necessarily take place.
