Learning disabilities: Understanding the difference between modifications and accommodations

http://www.helium.com/items/1541928-accommodation-and-modification

Excerpts:
"When modification is used, the outcome of the lesson's content is changed. The student is expected to learn something different than the general education standard"

"Accommodations and modification are two different entities. Accommodation gives students help with acquiring the contents of a course, whereas modification changes what is expected from the student. Either way, the two tools are there to ensure that students with disabilities are not left behind, in terms of education. It doesn't matter how much a teacher will worry or an administrator frets over these tools, by law they have to comply with them."
