EvoFIT has undergone extensive evaluation through both rigorous academic research and by the police in field trials. These have involved use of the EvoFIT system by trained police practitioners for an extended period of time, and assessment of the number of arrests based on the composite image, utility as an investigative tool and subsequent conviction. As the EvoFIT system has been improved (through carefully designed assessments to mirror the real world situation as far as possible), effectiveness has increased progressively. In the most recent evaluation, the suspect identification rate is approximately 60 percent, following construction of a criminal face image by witnesses and victims.
In over 20 years of research and development, EvoFIT has successfully been used in many police forces including: Avon and Somerset, Bedfordshire, Cambridgeshire, Cheshire, Cumbria, Derbyshire, Devon and Cornwall, Dyfed Powys, London (The Met), Greater Manchester (GMP), Hertfordshire, Humberside, Kent, Lancashire, North Wales, Scotland (Police Scotland), Northamptonshire, Northern Ireland (PSNI) and Staffordshire. EvoFIT has been used overseas in many countries, for example Austria, Boston, France, Israel, La Garda (ROI), Romania and the US.
