I was not previously familiar with Chandelier, but it appears to be more of a data organizing and storage system than an actual unique evaluative method. It might be a better articulated way of doing what good evaluators do anyway, which is to combine developmental and family history, setting/environmental factors, educational history, social/emotional/behavioral factors, instructional fit, etc. with direct and indirect psychometric data to formulate a learner's profile, in order to generate actionable recommendations.
The plus side of Dr. Tebbs philosophy appears to be that he is strengths-based.
