CITS COPA (AICET) key terms

The part of the COPA syllabus that explains why and how trade work is organised: the purpose of a trade, its tools, safety rules, and the standards a technician must follow. It is studied before hands-on practice.

The workshop-based part of the syllabus where a candidate performs real jobs with tools and machines. Skills are judged by the finished work, correct method, safety, and time taken rather than by written answers alone.

The applied mathematics and basic science used on the shop floor: measuring, calculating lengths, areas, volumes, angles, speeds, feeds, and understanding materials and simple machines. It supports both theory and practical work.

The non-technical abilities an employer expects: communication, teamwork, punctuality, workplace discipline, basic computer use, and awareness of safety and labour rules. These are assessed alongside trade knowledge in the AICET.

The All India Common Entrance Test used for admission to craftsman training and similar vocational courses. It tests trade theory, trade practical knowledge, workshop calculation and science, and employability skills through objective questions.

Crafts Instructor Training Scheme: a course that prepares skilled tradespeople to teach in industrial training institutes. Candidates learn instructional method, trade technology, and workshop management, and are often selected through an entrance test.

Computer Operator and Programming Assistant: a popular vocational trade covering computer fundamentals, operating systems, word processing, spreadsheets, databases, internet use, and basic programming. It prepares candidates for office and data-entry roles.

A trained person who teaches trade skills to trainees in a workshop or institute. The role combines subject knowledge with lesson planning, demonstration, assessment, and safe supervision of learners.

A teaching technique where the instructor performs a task step by step while trainees watch, then repeat it themselves. It is central to skill training because it shows correct procedure, posture, and safety in real time.

A written outline prepared before teaching that states the topic, objectives, materials, sequence of steps, and method of checking learning. It keeps instruction organised and ensures nothing important is skipped.

The process of judging a trainee's performance against set standards, using written tests, practical jobs, or observation. Results show what has been learned and where further practice is needed.

Actions taken before and during work to prevent injury or damage, such as wearing protective equipment, checking tools, keeping the floor clear, and switching off power before adjustments. They are compulsory in every workshop task.

Items worn or used to protect the body at work, including safety shoes, goggles, gloves, helmets, ear protection, and aprons. Correct selection and fit matter as much as wearing them.

Immediate, simple care given to an injured person before professional help arrives, such as stopping bleeding, cooling a burn, or keeping a casualty still. It aims to preserve life and prevent the injury worsening.

A tool used to determine a dimension or quantity accurately, for example a steel rule, vernier caliper, micrometer, or try square. Choosing the right instrument and reading it correctly decides whether work passes inspection.

The smallest measurement a particular instrument can read reliably. For a vernier caliper it is the difference between one main-scale division and one vernier division; knowing it tells you how precise a reading can be.

A measuring tool with a fixed main scale and a sliding vernier scale, used to read outside, inside, and depth dimensions. The vernier scale lets the user read fractions of the smallest main-scale division.

A precision measuring instrument using a screw and thimble to measure small thicknesses and diameters, commonly to hundredths of a millimetre. It is read by combining the barrel scale with the thimble scale.

The permitted amount by which a dimension may vary from its nominal value while still being acceptable. A drawing usually states upper and lower limits, and a part outside them is rejected.

Fit describes how tightly two mating parts assemble, such as clearance, interference, or transition fit. Allowance is the intentional difference in their sizes designed to produce that fit.

The system of specifying the largest and smallest permitted sizes of mating parts so they assemble and function as intended. Standard tables assign letter and number codes to holes and shafts.

The rate at which the cutting edge of a tool moves relative to the work surface, usually expressed in metres per minute. Too high a speed dulls tools and overheats; too low a speed wastes time and gives a poor finish.

The distance the cutting tool advances into or along the work per revolution or per stroke. Together with cutting speed it controls material removal rate, surface finish, and tool life.

A machining operation that produces a round hole by rotating a drill bit and pressing it into the work. Correct speed, feed, alignment, and clamping prevent drill breakage and inaccurate holes.

Cutting an internal thread in a drilled hole using a tap held in a tap wrench. The hole must be drilled to the correct tapping size, and the tap must be kept square and reversed periodically to break chips.

The vocabulary of screw threads, including pitch, major diameter, minor diameter, flank angle, and lead. These terms let a technician identify a thread and select the correct tap, die, or gauge.

A hand operation that removes small amounts of metal with a file to shape, smooth, or finish a surface. Correct stance, stroke, and file selection produce a flat, accurate surface.

Manual work carried out at a workbench using hand tools such as files, hacksaws, chisels, and taps. It develops control and accuracy and forms the foundation for later machine work.

A checking tool with a stock and a blade set at exactly ninety degrees, used to test squareness of edges and faces. The work is judged by holding the tool against it and looking for light gaps.

Joining metal parts by melting a filler metal with a lower melting point than the parts, which flows into the gap. Clean surfaces and the right flux are essential for a sound joint.

A joining process in which a non-ferrous filler metal melts above roughly four hundred and fifty degrees Celsius but below the melting point of the parent metal. It gives a stronger joint than soldering.

System software that manages hardware, files, and programs and provides a way for the user to run applications. Examples include Windows and Linux, and knowing basic operations is part of the COPA trade.

Using software to create, format, edit, and print text documents. Typical skills include setting fonts, margins, tables, spell check, and saving files in suitable formats.

Software that arranges data in rows and columns of cells and can calculate results with formulas. It is used for records, accounts, charts, and simple data analysis in office work.

An organised collection of related data stored so it can be searched, sorted, and updated efficiently. A database management system controls who may view or change records.

Use of connected networks to find information and exchange messages. Practical skills include using a browser, searching effectively, attaching files, and following basic safety and etiquette online.

The ability to give and receive information clearly through speaking, listening, writing, and body language. At work this includes reporting faults, taking instructions, and writing short, accurate notes.

Working cooperatively with others towards a shared task, sharing information and supporting colleagues. It requires listening, accepting responsibility, and resolving small disagreements politely.

Following the rules and routines of a workplace: arriving on time, wearing correct dress, caring for tools, completing assigned work, and respecting supervisors and co-workers. It is a key employability expectation.
