What should a school psychologist insist on when evaluating students, according to NASP ethics?

When evaluating students, a school psychologist should insist on administering the most recent form of valid assessments. This approach aligns with NASP ethics, which emphasize the importance of using current, evidence-based practices in the evaluation process. By utilizing up-to-date tools, psychologists ensure that the evaluations are reflective of the latest research findings and methodologies, thus improving the validity and reliability of their assessments.

Using valid assessments that incorporate the most recent developments in the field helps to accurately assess a student's strengths and needs, guiding effective interventions and supports. It also ensures compliance with ethical standards, which require that psychologists provide services based on a solid foundation of scientific knowledge and practice.

In contrast, relying on outdated tools can compromise the quality of the evaluation and potentially lead to inappropriate educational decisions for students. Creating one's own evaluation tools may not meet the necessary psychometric standards and could yield unreliable results. Similarly, choosing tests based solely on their popularity may disregard the specific needs of the students and the context in which they are being evaluated, possibly leading to biased or ineffective support strategies.
