Chapter 8 is concerned with the practical use of ECT, especially building an ECT-based assessment-guidance system. Four instruments are conceptualized and designed for the purpose: (a) talent potential indicators, which assess aptitudes and dispositions relevant to bioecological effectivities; (b) talent PAS indicators, which assesses characteristic adaptation (CA); (c) talent driver indicators, which assess four types of personal strivings; and (d) talent milestone indicators, which assess achievement or psychosocial milestone events. The first two instruments are mainly for talent identification, and thus are more useful in the exploratory stage of TD, and the last two instruments can be used across the board for assessing where the person stands with respect to the pursuit of excellence. For each instrument, an interpretation scheme is presented to assist in its use for guidance and counseling purposes.
