What type of documentation is required when a student must be coached on performance or behavior?

The correct choice is the Individual Education Plan (IEP) because it serves as a formalized document outlining specific educational goals and accommodations for students who need additional support. When a student requires coaching on performance or behavior, an IEP ensures that there is a structured approach to address their unique needs, including strategies for improvement and goals to be achieved.

The IEP is particularly significant in cases where a student's challenges may stem from learning disabilities or other conditions that affect their ability to perform or behave in a learning environment. It typically involves input from educators, specialists, and the student’s parents or guardians to create a personalized plan.

In contrast, other options such as a Progress Report, Behavioral Plan, or Curriculum Adjustment Document may serve different purposes. A Progress Report provides updates on a student's performance but does not set specific goals or strategies like an IEP does. A Behavioral Plan focuses on managing behavior specifically rather than the broader educational framework provided by an IEP, which encompasses various aspects of a student's education. A Curriculum Adjustment Document might outline changes to the curriculum to meet student needs but lacks the detailed focus on individual student requirements found in an IEP.
