Some of these Titles and Initials, such as Chartered Engineer (C.Eng), mean nothing to most people and are impracticable in this modern age, since they cannot become international. Some are outdated and are a carry over from Colonialism. Chartered Engineer has only legal significance to offer.
In the UK there are the initals ‘EngTech’ in use. It is internationally accepted that the initials ‘Eng’ means ‘Engineer’ and ‘Engg’ means ‘Engineering’  so, ‘EngTech’ means ‘Engineer Technician’. Idiotic, with more confusion!


We are all aware of people who give themselves titles that they hope will improve their image in society. Some of these titles have been with us for very many years with more arising each day. For example we have the ‘Tree Surgeon’ and the ‘Drains Doctor’……….fancy titles for fancy jobs!
Anyone can himself a Doctor and carry out medical procedures, even operations, once they obtain consent from the patient. As well, anyone can call himself a Lawyer, and practice as a Lawyer, but cannot represent a client in a court of law unless they are licensed.
The ‘Engineer’ title still seems to be a free-for-all. Engineers seem to be, in general, targets from people with a little technical knowledge mainly, but some don’t even have technical skills. We have the ‘Train Driver’ who calls himself a ‘Locomotive Engineer’, especially in US, Canada and South Africa. Their argument is that they had the title ‘Engineer’ first. Surely the ‘Train Driver’ did not exist before the first train was designed and built by Engineers!! ( Ref : Engineer George Stephenson 1814 ). Then we have the ‘Stationary Engineer’ who is a Plant Attendant and the ‘Motor Engineer’ who is in fact a Mechanic. The latest to the list is the ‘Nail Engineer’ who is a manicurist!
Then we have the ‘Drains Engineer’ who cleans drains. We also have Fitters, Plumbers, Mechanics and other Craft Persons, etc., who call themselves ‘Service Engineers’, or ‘Installation Engineers’, or ‘Heating Engineers’, or some such. These are not even qualified to the modern day ‘Technicians’ standards let alone that of ‘Engineers’. The latest addition to the list is the ‘Satellite Engineer’ who is in fact a TV Satellite Dish Installer. This title is arrogantly and disrespectfully being promoted by the UK based SKY Media Group in foreign countries, irrespective of local standards. The unfortunate thing about all of this is that it discourages bright young pupils from seeking a professional engineering career, which is intellectually demanding, as they are confused about their future identity in society and their recognition for professional achievements.



Everyone knows what a Doctor does in his Professional life and what his Technician does. Similarly it is well known what the other professionals such as Veterinarians, Accountants, Architects, etc., and their Technicians do in their Professional careers. However, a survey has shown that 80 % of the general public don’t know what Engineers do in their Professional careers and their relationship to eTechnologists and eTechnicians. This is due to the fact that the general public have no everyday dealings with Engineers, other than the occasional contact with Civil Engineers.
Engineers are concerned with developing economical and safe solutions to practical problems, by applying mathematics and scientific knowledge while considering technical constraints.

An Engineer’s Professional work can be very interesting, varied, and financially rewarding. His basic training is in technical design. His work can vary from using his mathematical and scientific expertise to explore the planet, to the design of mobile phones, computers, robots, rockets, spacecraft, satellites, radar equipment, digital television transmitters, hospital life-saving equipment, PET, CT, and MRI scanners, X-Ray machines, pacemakers, automobiles, aero planes, bank cash-machines, digital cameras, music and video systems, guns , ammunition, household appliances, and even gadgets, etc. Very many significant advances in medicine over recent years can be attributed to engineers. They design body scanning machines such as PET (positron emission tomography), CT (Computer tomography), and MRI (magnetic resonance tomography) scanners. They also design such equipment as dialysis machines, heart machines, heart pacemakers, prosthetic devices, X-Ray and Ultrasonic equipment, artificial body replacements, hospital monitoring equipment, and other types of life-saving equipment. The latest, many years in development, the i-LIMB Hand is a prosthetic device that looks and acts like a real human hand with five individually powered digits, heralding a new generation in bionics and patient care.
………. the list is endless!

Very many Engineers are involved in Engineering/Science research.

‘Mechatronics’ (Mechanical and Electronics Engineering) is the combination of Mechanical Engineering, Electronic Engineering and Computer Engineering. The purpose of this interdisciplinary engineering field is the study of automata from an engineering perspective and serves the purposes of controlling advanced hybrid systems. The word itself is a portmanteau of ‘Mechanics‘ and ‘Electronics’.

Specialized engineering fields are numerous and include,
Aerospace · Agricultural · Architectural · Audio · Automotive · Biological · Biochemical · Biomedical · Broadcast ·Ceramic · Chemical · Civil · Computer · Construction · Cryogenic · Electrical · Electronic · Environmental · Food ·Industrial · Materials · Mechanical · Mechatronics · Metallurgical · Mining · Naval · Network · Nuclear · Optical ·Petroleum · Radio Frequency · Software · Structural · Systems · Technician · Textile · Tissue · Transport.



‘PROFESSIONAL ENGINEER’ is the term for an International Licensed Engineer who is permitted to offer professional services directly to the public. The term Professional Engineer and the actual practice of professional engineering is legally defined and protected by a government body. In some jurisdictions only registered or licensed Professional Engineers are permitted to use the title, or to practice Professional Engineering. A “Professional Engineer” must have 8 years post-graduate professional experience and must pass an examination set by the relevant Professional Body. His work is basically technical design, but very many end up in senior management and other fields.


An ‘ENGOLOGIST’ is an International Graduate Engineer with an approved technical engineering degree, or equivalent.


eTECHNOLOGIST  (Engineering Technologist)
A Professional ‘Engineering Technologist’ is normally someone with a qualification in technical or software engineering or equivalent . His work is normally supportive to the Engineer in such areas as computer aided design (CAD). This relieves the engineer of less demanding work. It was designed to effectively bridge the gap between the increasingly theoretical nature of engineering degrees and the predominately practical approach of a technician.


eTECHNICIAN (Engineering Technician)
An ‘Engineering Technician’ (eTechnician) is normally involved in practical engineering work and holds an approved engineering diploma or equivalent . Their work can be the repair of sophisticated equipment such as computers, printers, scanners, refrigerating equipment, televisions, instruments, telephone systems , and household appliances such as fridges , washing machines , cookers, CCTV, and even digital cameras, etc. They can also be involved in installation work such as the installation of burglar and fire alarm systems and the repair of same, to the installation and maintenance of gas installations, and commercial equipment such as that used in aircraft and in industry etc . There are many types of specialist technician, software technician, installation technician , service technician , instrument technician, computer technician, aircraft technician, sound technician, audio technician, engineering technician , telephone technician, broadband technician.


There are very many types of engineering ‘Operators’. There are Control Room Operators in Power Stations, Sound and Vision Operators and TV Operators in Radio and TV Stations, Theatres, Cinemas, etc. Also, there are Plant Operators who operate all kinds of plant and machinery in industry.


Recordists are employed by Radio and TV Stations. They record sound and video programs for transmission. Recordists also record in Recording Studios for DVD’s, CD’s, etc.


The word Techie is a general respectful term used to describe someone with skilled technical knowledge. Because of the many different categories of Engineering worker with technical knowledge, ‘Techie’ is used as a general title by people who might not be familiar with the titles of the different categories. As well, since there is much overlap between the different categories, the general title ‘Techie’ will suffice to describe a skilled technical worker.
In days of yore the general blanket term used by some was ‘Engineer’ to cover the different categories of engineering workers. In this advanced technological age it is important that the title ‘Engineer’, which is ambiguous at present, is well defined for safety and other reasons, hence the need for the new title ‘Engologist’ which brings clarity.


An Installer is normally a person skilled in the practical aspects of installation work but limited in the theoretical aspect, e.g., Telephone Installer, Broadband Installer, Burglar and Fire Alarm Installer, Gas Installation Installer, Aerial/Satellite Dish Installer, etc. For complex installations you would have a commissioning Technician. Servicing would then be carried out by a Service Technician.


A Mechanic is someone who uses his skills to repair vehicular appliances, aircraft engines and other machinery . In general, anything with moving parts. You have car mechanics, aircraft mechanics, instrument mechanics, etc.


A  Fitter is normally associated with the repair of heavy machinery such as that used in industry. They install and repair gas boilers and systems. They also repair such equipment as fire extinguishers, cookers, air conditioning systems, escalators, passenger lifts, industrial boilers and systems, commercial refrigeration systems, heavy earth-moving equipment such as bulldozers, etc.


A Plumber is a person who fits and repairs pipes and fixtures for water, drainage, or gas, mainly in domestic premises. Plumbers also install and repair gas/oil domestic and commercial central heating boilers and systems.


An Electrician is someone who installs/repairs electrical equipment. In some countries electricians are licensed. Their work involves the installation and maintenance of anything that is powered by electricity. This can be domestic appliances such as fridges, cookers etc. Their work varies from the installation and maintenance of domestic and commercial equipment and installations to the supervision of maintenance and operations of very high voltage lines such as that in National Grids.


Linesmen install and maintain telephone lines and also overhead Power lines including High Voltage lines as used in the Electricity National Grid.


An apprenticeship can be defined as ‘A formal system by which an employer undertakes by contract, written or implied, to employ a person and to train them or have them trained systematically for a trade or occupation, the apprentice agreeing to work in the employers service’.


An Artisan is a skilled person who makes things by hand.
There can be some overlap between some of the above categories of trade persons .
