A full year. One cohort. One certification. The Complete Pathway Cohort takes the entire CORE 4 clinical curriculum courses — Art & Science, VT1, VT2, and VT3 — and delivers it as a single, immersive year: six three-day weekends, rotating senior faculty, hybrid hands-on training, and a small cohort you'll grow alongside. Complete the full pathway and earn your certification — built for practitioners, therapists and students ready to commit to the whole journey at once, with flexible payment and an optional in-person capstone weekend to close out the year.
By the end of the year, participants leave with the complete CORE 4 skill set and certification — not just four sets of course notes, but one integrated clinical practical foundation-built weekend by weekend.

The Evolution of a Model and A Model of Vision (Read The Evolution of a Model first.) are included to introduce you to our approach to teaching. These two papers describe the process for much of what comes in the courses and we hope you understand that we instructors evolve in our thinking much like we hope you will. We hope to take you on a compressed journey through the evolution of our thinking. We will begin an area by showing you where we were at one time in our development. Then we present the unanswered questions that became the foundation for looking at things in a different way. We will then present our understandings now and include new information for where we might go in the future.
The Evolution of a Model was presented at the Skeffington Symposium in Washington DC in the early 1980’s. This paper charts the development of Paul Harris’ model of vision from what he assimilated from his years at SUNY (1975-79) until the time of the writing of the paper. Much of the change came as a result of a presentation by Dr. Robert A. Kraskin and involvement in the Washington DC based OEPF study group, the Institute for Behavioral Optometry. A Model of Vision was initially presented at the Skeffington Symposium in Washington DC and then adapted for the JOVD.
