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

Part II tests six clinical science areas (domains):

  • General Diagnosis
  • Neuromusculoskeletal Diagnosis
  • Diagnostic Imaging
  • Principles Of Chiropractic
  • Chiropractic Practice
  • Associated Clinical Sciences

Each domain consists of 50 standard multiple-choice questions.

Part II 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.
