Diploma in Operation Theatre Technology
Diploma in Operation Theatre Technology (DOTT) is a two-year, post-Class 12 diploma that trains students to assist surgical and anaesthesia teams and manage equipment, sterilisation and patient care inside the operation theatre. There is no single national regulator exclusive to this diploma; institutes are affiliated to state universities or health boards, and the National Commission for Allied and Healthcare Professions (NCAHP) is the emerging central body for allied health professions. The curriculum covers anatomy and physiology, operation theatre organisation, sterilisation techniques, anaesthesia technology basics and surgical instruments, combined with supervised clinical postings in hospital operation theatres. DOTT suits Class 12 science students who want a hands-on, clinical support career in surgical care.
