What is Part I?
Part I is a computer-based test, delivered on chiropractic college campuses.

Part I tests six basic sciences areas (domains):

  • General Anatomy
  • Spinal Anatomy
  • Physiology
  • Chemistry
  • Pathology
  • Microbiology

Each domain consists of 50 standard multiple-choice questions.

Part I is divided into three sessions; each session consists of two domains. Each domain is allotted 42 minutes with an optional 15 minute break after each of the first two sessions. Testing appointments are 5 hours.
