understanding graphing is fundamental to diagnostics


Diagnostic Tools (d-TOOLS)

d-TOOLS provides self-paced learning, delivered in short chapters to maintain interest and optimize learning. By teaching this material online, we are limiting the use of expensive classroom time for training in tactical development and execution. In 8 hours, you can complete d-TOOLS training.

Self-paced online learning has several distinct advantages over the classroom:

  • Consistent and professional delivery
  • Student testing, monitoring, and college credit in some cases
  • Translation to other languages, while maintaining consistent delivery


And not the least of which is the efficiency of delivery and at a fraction of the cost of the classroom. Two hours of high quality self-paced training can replace eight hours of classroom time, leaving the classroom for tactical discussions and development.
