Tawjihi Vocational Engineering study guide
Tawjihi Vocational Engineering · Work through your exam, one topic at a time.
The Tawjihi Vocational Engineering stream is the Jordanian general secondary certificate pathway for students preparing for technical careers or further technical study in engineering fields. It suits candidates who prefer applied, hands-on learning over purely academic tracks and who intend to work as technicians, drafters, maintenance staff, or to continue into vocational or engineering programmes. The Tawjihi Vocational Engineering study guide has 12 sections and about 3,740 words.
01Engineering Drawing and Technical Graphics
This domain tests drawing literacy rather than freehand skill: projection layout, line convention, dimensioning rules, sectioning and the tolerance notation that turns a shape into a manufacturable instruction. Questions usually ask you to identify correct view placement, a missing dimension, or the meaning of a symbol.
344 words, about 2 min02Engineering Materials and Workshop Technology
This domain covers what parts are made from and how they are cut, formed and finished in the workshop. Expect classification of ferrous and non-ferrous metals, the purpose of each heat treatment, tool selection, and cutting calculations for drilling and turning.
308 words, about 2 min03Applied Mechanics and Statics
This domain tests whether you can replace a real machine part with a free-body diagram and solve it. Expect vector resolution, equilibrium of concurrent and non-concurrent forces, moments, friction, and the basic stress and factor-of-safety relationships that link statics to design.
334 words, about 2 min04Electrical and Electronic Fundamentals
This domain checks that you can analyse a circuit rather than memorise a formula sheet: Ohm's law, series and parallel networks, power, Kirchhoff's laws, AC quantities, and the behaviour of the diode and transistor as a switch. V = IR; P = VI = I²R = V²/R.
301 words, about 2 min05Manufacturing and Production Processes
This domain covers how a finished part is produced: casting and moulding, bulk and sheet forming, joining, machining, and the production-system choices behind them. Questions favour allowances, process selection and defect recognition.
315 words, about 2 min06Measurement, Instrumentation and Quality Control
This domain tests instrument reading, limits and fits, gauge use, calibration and the statistical control of a process. Expect at least one direct reading question and one tolerance calculation.
310 words, about 2 min07Occupational Safety, Health and Environmental Practice
This domain tests hazard awareness and the control logic behind safe systems of work: risk assessment, the hierarchy of controls, machine and electrical safety, fire response, chemical handling and waste management. Risk = likelihood × severity, scored on a 5 × 5 matrix.
326 words, about 2 min08Maintenance and Troubleshooting of Machinery and Equipment
This domain tests maintenance strategy selection, reliability numbers and fault-finding discipline. Expect calculation of MTBF, MTTR and availability, plus questions on condition monitoring and root-cause analysis.
281 words, about 1 min09Engineering Mathematics and Applied Calculations
This domain checks calculation fluency applied to workshop and design problems: SI units and prefixes, areas and volumes, Pythagoras and trigonometry, ratio and gear trains, taper, percentage and sensible rounding. Prefixes: k = 10³, m = 10⁻³, µ = 10⁻⁶.
266 words, about 1 min10Technical Communication and Workplace Documentation
This domain tests whether you can record, transmit and control technical information so that a job can be repeated and audited. Questions cover the title block, work orders, inspection and nonconformance records, revision control, and clear report writing.
301 words, about 2 min11Entrepreneurship, Project Planning and Costing
This domain tests whether you can turn a technical skill into a viable small enterprise and then plan and cost the work. Expect the business model canvas, cost classification, break-even arithmetic, cash-flow awareness and simple project scheduling.
321 words, about 2 min12Project Planning and Costing for Engineering Work
This domain applies planning and estimating discipline to engineering jobs: sequencing activities, finding the critical path, estimating labour and material, and monitoring progress with earned value. It is the costing companion to the entrepreneurship domain, focused on delivering a contracted scope.
