This Education Week commentary lays out major issues in principal selection and offers solutions. Armed with a solid benchmarking process, schools, including university schools of education, can screen applicants and ultimately hire a new generation of more effective leaders.
This is the original technical, entrepreneurial write up showing that the TTI Performance TriMetrix® DNA assessment data differentiates a target group of serial entrepreneurs from a sample of the general population. Further, follow on studies plan to extend the logistic regression technique to include a predictive model building approach and subsequent predictability studies as relevant data comes available.
This paper starts with a summary marketing take away section that then leads to the original “Classification of Serial Entrepreneurs via Logistic Regression: A Case Study”
A key area for any assessment is whether the assessment data may be used, in some form, to generate a predictive model. The results are very solid and provide solid support for a follow on, longitudinal study to determine the potential predictive power of such a modeling approach.
Temporal consistency (a form of test-retest) is one of many forms of reliability that help establish an assessment as fully reliable and valid. This report of 7,742 individuals provides continuing evidence of temporal consistency, which adds to the argument that the TTI SI Styles Insights assessment has test-retest reliability.
This test-retest pilot study included 86 participants who took the behavioral assessment twice with an average separation of 38 days. The comparison showed no significant difference in the two reports and reliability was above 0.8 on both natural and adapted constructs.
One way to establish different forms of validity is to run comparison studies against known, established psychometric assessments. In this study, the TTI Success Insights Style Insights® behavioral assessment is compared with the Big Five Personality Inventory on a population of US university students. In general, the study shows some interesting correlations, but more importantly, the study shows that these two assessments are measuring different constructs.
One way to establish different forms of validity is to run comparison studies against known, established psychometric assessments. In this study, the TTI Success Insights Style Insights behavior assessment is compared with the Big Five Personality Inventory on a population of USA working adults. While the study shows some interesting correlations, it also demonstrates that these two assessments are measuring different constructs.
