What constitutes a valid assessment for students with disabilities?

The selection of evaluation by qualified personnel as the correct answer highlights the importance of expertise in assessing students with disabilities. Valid assessments for these students require trained professionals who understand the unique challenges and needs that may arise. Qualified personnel are equipped to select appropriate assessment tools, interpret results accurately, and understand how various disabilities can affect a student's performance.

This expertise ensures that the assessment is not only valid but also appropriate, catering to each student's individual needs, which ultimately supports the development of effective educational strategies tailored to help them succeed. When qualified personnel conduct evaluations, they are also more likely to adhere to ethical guidelines and best practices that govern special education assessments.

In contrast, the other choices do not provide a valid framework for assessing students with disabilities, as they may involve averages, biases, or unqualified opinions that fail to reflect the true abilities and needs of the students.
