OTS has helped me to better understand my son in a systematic way, with clear and understandable orientations. By using OTS Fingerprint Biometric service, I have been able to expand my knowledge of potentials. the ability of people in general and their children in particular. One thing I found very impressive in OTS's service. That's how you counselors interact with girls and boys when you come for a fingerprint sample. The kids are very happy and feel interesting.
