Quick, Accurate, and Reliable

Founded with a single, simple mission: For you to have a clear knowledge of your strengths. So, you can better live from your strengths. And, have greater joy and success.

  1. PDP’s survey instruments were researched and developed by credentialed professionals, research experts, behavioral scientists, and experienced leaders in business and industry.
  2. Initial research sample consisted only of working adults—not students. PDP wanted to develop applications to meet the needs of working population. Student samples are easier to obtain, but PDP was committed to laying the best foundation of research possible.
  1. Average completion time of PDP survey instruments is 5-10 minutes, providing users with quick, accurate data to make critical decisions about their people.
  2. Survey instruments deliver the highest level of accuracy, greatest amount of depth, and widest scope of information available from any survey instrument on the market today.
  3. Survey reporting and graphic results are instantly generated and available via email or through PDP’s easy-to-navigate web application,
  4. All PDP products and methodologies meet EEOC requirements, and have never been challenged in court.
  5. PDP is unparalleled in accuracy, practicality, fairness, and value.


Research Studies & Information

We are proud that PDP is based in scientific research conducted alongside leading behavioral scientists and focused entirely on the working adult population. We have not set out to prove a theory and do not study students to try to understand professionals, instead we go straight to the source – working population – and develop programs in response to findings. The result is a top notch way of helping people understand themselves and experience success.


Stringent Research Parameters

Since the beginning, stringent research parameters have been used so all PDP system results are as accurate as they can be. The industry standard for correlating coefficients is only 60%, but the PDP standard is at minimum 80%. Research is based on stimuli response rather than relying solely upon a self-perception method, helping garner real-world applicable results. A variable norm is used to accurately determine individual strengths in comparison to other strengths rather than to population norms. These standards help us offer a comprehensive and complete assessment that can be used to place employees, help team members work together, and empower managers.


Validation Studies

We also participate in validation studies to help show the continuous applicability of all PDP system results. These studies are designed to measure effectiveness and accuracy as well as ensure that PDP systems are always relevant.
