- In educational assessment this includes Computer Adaptive Testing (CAT) to achieve greater efficiency, as well as Automatic Essay Grading (AES) where students’ essays are graded by computer.
- In financial technology (FINTECH), IKS pioneered the use of psychographic data to obtain reliable credit ratings. Using this approach banks can now provide loans to meritorious – but often under-served – groups, like minorities or women, that may lack extensive credit histories.
- In tourism and hospitality, IKS has a long history of providing new assessment approaches to screen and select personnel at varying levels.
