What follows is the outcome of a reliability and validity study as performed by Karin Roodt, M Ed (Counselling and Guidance) UNISA, Registered Psychologist (SAMDC), Senior Lecturer, Technikon Natal (serving as Project Manager), assisted by Charles Robert, BSc (Hons)(Stats): Statistician, Director of South Africa on Line.

I would like to thank the following companies and individuals for participating in this study and in some way contributing to the final report:

• Edgars Group Gauteng
  Wayne Suelz, Recruitment and Assessment Specialist: Human Resources Department
• Toyota SA.
  François Viljoen, Mark de Wet and the rest of the dynamic team in the Department of Human Resources Management
• BB Cereal
  Gill Gibson (Mrs)
• NBS
  Natasha Carsens (Mrs)
• Technikon Natal
  Leslie Jordaan, Director: Personnel (Durban), Craig Stewart: Personnel (Pietermaritzburg) and Ann du Toit (editing)
• HSRC
  Barbara Miller and Berryll McIntyre for assisting with the marking of Technikon Natal's 16-PF answer sheets
• Labour Lawyer
  Graham Giles for scrutinising this report from a law perspective.

A study of this nature must be approached with caution because no single psychological tool is able to yield everything about a person's personality. A test battery, i.e. a collection of several tests, reveals far more about an individual than does any single test of personality, preference, interests, intelligence or general personality dynamics.
