The document summarizes an aptitude, personality, and interest assessment tool called iDC that was developed over 2 years and launched in late 2013. It describes the stages of pilot testing on over 31,000 students. It explains the theories behind each part of the assessment - aptitude draws from Carroll's CHC model, personality from the Big 5 model, and interests from Holland's RIASEC types. Reliability testing found Cronbach's alpha scores in the desirable 0.6-0.9 range. The tool assesses 16 factors across aptitude, personality, and interests. It has been used in government programs, non-profits, and schools in India and abroad, assessing over 21.5 lakh students

3. • Aptitude Test – CHC theory (Carroll’s model)
– 3 stratum structure of intelligence (Narrow, Broad & general
ability)
– Proposes large number of distinct individual differences in
cognitive abilities
– CHC theory narrowed down to Numerical, Verbal, Mechanical,
Spatial & Reasoning aptitude.
– Research evidence indicates these abilities play significant role
in influence performance across different career profiles

6. • Reliability statistic of the tool has been calculated using
Cronbach Alpha.
– Aptitude Test - ɑ= 0.64
• Item Difficulty and Point Biserial (p values) were also calculated for
each items (90% items were in the acceptable scores)
– Personality Test - ɑ= 0.79
– Interest Test - ɑ= 0.78
• Desirable range of acceptability for C.Alpha is between
0.6-0.9.
