Validated by 30 years of science and research from Target Training International, we are committed to constantly improving our assessments. Data norming, structured equation sampling and rigorous data analysis help ensure our assessments are the most validated tools in the marketplace.

Scale reliabilities were calculated using Cronbach’s alpha (α), which is considered
 the most appropriate statistical test for calculating reliability. The statistic models internal consistency, based on the average inter-item correlation. These evaluations are a more rigorous approach than a traditional split-half statistic. Cronbach’s α is a statistic bounded by zero to one. In general, an α equal to or greater than 0.6 is considered a minimum acceptable level, although some authorities argue for a stronger standard of at least 0.7. TTI’s Behaviors assessments scored a minimum of 0.826.


TTI’s Motivators assessments contain twelve frames of six phrases each. Each phrase is an indicator of one the six latent motivations. Respondents rank order the six items from one to six, with number one being their highest ranking of the statement, down through number six being their lowest ranked statement. Scales are constructed by reversing the rankings, summing 
up related items’ ranks, and adjusting the score upward to avoid possible zeroes. Results from TTI’s Motivators assessments indicate trustworthy reliability for all six scaled with Cronbach’s alpha (α) ranging from 0.7 to 0.8.


TTI’s DNA Talent, measuring competencies, is a 360-degree feedback type instrument, and for validity purposes we evaluate each of the questions on a variance scale. Our 2012 data indicates complete variance for this questionnaire.


TTI’s Hartman Value Profile, measuring acumen, has an internal reliability measurement, and our 2012 data indicates a part one reliability of .897 and a part two reliability of .825.

Emotional Intelligence/EQ

Our Emotional Intelligence (EQ) assessment is based on a multidimensional view of EQ. Our EQ score are normed based on the standard bell curve, which results in 16 percent of individuals scoring “low,” 68 percent of individuals scoring “average,” and 16 percent scoring “high.” Using test-retest reliability, all reliability estimates exceed the minimally acceptable level of .770, thus showing that our EQ assessments measure behavioral tendencies consistently and reliably.
