The PLOP should describe the child's current level of ability. Usually, good IEPs list a separate PLOP for each section or topic or skill area. The PLOP is generally several sentences, and is written in a narrative style. The PLOP is an excellent place for including parent input and observation.
Objectives are very specific and measureable.
It is a teacher goal or methodology. Participation in general education, with needed support services, should be the starting point, rather than the other way around. The IEP should list all the accommodations or modifications needed for success in the general education classroom, too. IEPs should also list the adaptations or modifications your child needs to participate in district-wide standardized testing. Only students for whom modifications or accommodations invalidate performance on the tests, or for whom the IEP Team agrees the tests are not appropriate can have other forms of assessment written into their IEP instead of standardized testing.
