Tamara, a school counselor, suspects a 5-year-old student may have Autism Spectrum Disorder. She decides to use the Adaptive Behavior Assessment (ABAS-3) to formulate a diagnosis. However, she only has access to an earlier version of the assessment tool. Tamara believes that if the earlier version was adequate before, the results will still be helpful. She administers the assessment with the guardian's permission and shares her findings of an Autism Spectrum Disorder diagnosis with the school's principal and the student's teachers. Using an ethical decision-making model, discuss Tamara's decision-making process and how she may handle this situation similarly or differently in the future.
