Under IDEA, when can a child with a disability be placed in an interim alternative educational setting?

A child with a disability can be placed in an interim alternative educational setting under IDEA specifically when they bring a weapon to school. This provision is part of the law designed to ensure safety and to maintain a conducive learning environment. The law allows for such placements to serve both the educational needs of the child and the safety concerns of the school community.

In this context, an interim alternative educational setting provides students with educational services while addressing behavioral issues that may pose safety threats. This placement can be utilized for specific serious behavioral violations, including the possession of weapons, which is treated with particular severity under IDEA to protect all students.

Other scenarios such as needing additional services, displaying emotional disturbances, or placements based solely on a parent's request do not trigger the same legal framework for interim alternative settings as the possession of a weapon does. Therefore, option B aligns with the specific regulations under IDEA focused on maintaining safety and addressing serious behavioral issues.
