Which of the following describes a key component of triennial reevaluation?

The key component of triennial reevaluation is that it assesses a student's needs and abilities at least every three years. This process is essential in ensuring that the educational program continues to meet the evolving needs of the student with disabilities. By conducting a reevaluation every three years, educators and specialists can gather updated data on the student's current levels of performance, strengths, and any areas that may require additional support or intervention. This helps to make informed decisions about necessary adjustments to the student's Individualized Education Program (IEP) and ensures compliance with legal requirements.

In this context, focusing solely on academic performance or requiring parental presence is not a comprehensive aspect of the reevaluation process. Triennial reevaluations also do not occur only after major changes; rather, they are a scheduled part of the educational process to monitor and support the ongoing development of the student.
