During which decade was the first NASP exam conducted?

The first NASP exam was conducted in the 1990s, specifically in 1998. This exam was established to provide a formal assessment for those seeking national certification in school psychology, reflecting advancements in the field and the need for standardized credentialing. The decade marked a pivotal time for the profession, as school psychology was gaining recognition and standardization among educational systems.

In contrast, the other decades mentioned either do not align with the timeline of significant formal assessments for school psychologists or precede the establishment of NASP as a professional organization dedicated to the practice.
