Cassandra believes that high-quality assessment requires more than learning test administration procedures. Effective assessors need a strong foundational assessment skills including deep understanding of each of the tools they use and the psychometrics of the tools, critical thinking skills, awareness of their professional limits, and ongoing supervision to refine their judgment. These principles form the foundation of Lighthouse’s training philosophy and guide every course, workshop, and supervision experience she provides.
