The Professional Technologist (PTech) or Certified Engineering Technologist (CET) or Applied Science Technologist (AScT) is a professional capable of assuming and exercising independent judgement to develop and manage technology. This is achieved by the accumulation of academic training and related experience in the application of known principles of sciences and mathematics. The certified technologist is a graduate of a nationally accredited technology diploma program (typically two or three years duration) or equivalent, who has completed two or more years of progressive experience in an area of work directly related to the program and who has received favourable supervisory references.

The Professional Technologist has studied a curriculum based upon a core of applied sciences which will be used in solving technical problems or managing technology. The curriculum includes the fundamentals of applied science or engineering technology applicable to a particular discipline or specialty of technology. The academic and theoretical portions of the technical curriculum is reinforced by suitable laboratory experiments, exercises and field work amounting to approximately one third of the total program.

The Professional Technologist may carry out a wide range of complex analytical work either independently or under general direction in fields such as engineering, architecture, building, surveying, bio-science, chemistry and resource or systems management. Typical activities include design, production, marketing, testing, quality control, estimation, surveying, inspection, diagnostic evaluation, supervision, management, technical sales and teaching. Such activities may be carried out in association with other professionals.

The Professional Technologist uses an applied approach based on a comprehensive understanding of a specific technology. The technologist evaluates assignments, determines procedures and implements solutions, schedules work to meet objectives, participates in short and long-range planning and may become involved in developing and promoting conceptual change.

Technologists may assume managerial or administrative responsibility for a wide range of technical endeavours. The technologist may supervise and coordinate a diverse working group and train less experienced technical and professional staff. The certified technologist is bound by a professional code of ethics, the Engineering Technology Act of New Brunswick, and is recognized by either the designation PTech, CET, or AScT throughout
