Experience
For 40 years, SIGMA Assessment Systems has been researching and publishing psychological assessment
tools, and supporting these tools through consulting services. Highly experienced in leadership
selection and development, a strong focus has centered on the construction and validation of a
quality 360 feedback assessment. The value of SIGMA's work in the 360 arena is exemplified by the
use of the instrument in eight countries and six different languages. Our team of professionals
includes industrial and organizational psychologists and experienced software developers. SIGMA has
successfully completed 360 feedback processes for organizations ranging from as few as three to as
many as 35,000 employees.
Quality
The founder of SIGMA Assessment Systems, Douglas N. Jackson, Ph.D.,
was a world authority on testing, assessment and performance
appraisal. The SIGMARadius 360 degree feedback tool
was developed according to Dr. Jackson's strict standards
of excellence in testing.
Confidentiality
The success of any 360 feedback process depends on the anonymity of the ratings.
As a founding member of the Association
of Test Publishers, SIGMA is committed to the highest standards of client confidentiality.
SIGMA uses every possible safeguard to ensure complete confidentiality.
