ITI to Diploma Engineering - I.T.I.E.C.E.
What the paper tests
I.T.I.E.C.E. is the JCECEB lateral-entry route for ITI passouts seeking diploma engineering admission. It tests trade theory, workshop calculation and science, engineering drawing, basic mathematics and physics, and workshop safety. The trade paper is aligned to the candidate’s ITI trade, such as fitter, electrician, welder, machinist or COPA.
Core rules and concepts
- Trade theory: tools, materials, processes, measuring instruments and trade-specific terminology.
- Workshop calculation: cutting speed, feed, taper, gear ratio, area, volume and percentage.
- Engineering drawing: orthographic projection, dimensioning, symbols, limits and fits.
- Safety: PPE, electrical isolation, fire classes and machine guarding.
- Basic science: force, work, power, energy, Ohm’s law and material properties.
Worked example
Find the cutting speed for a 50 mm diameter job rotating at 400 rpm. Cutting speed (v = \pi DN/1000) m/min. So (v = (3.1416 \times 50 \times 400)/1000 = 62.8) m/min. The reasoning: diameter must be in mm, N in rpm, and the divisor 1000 converts mm/min to m/min.
Traps that cost marks
- Mixing mm with m when using the cutting-speed formula.
- Reporting rpm as cutting speed; rpm is spindle speed, not surface speed.
- Confusing first-angle and third-angle projection symbols.
- Forgetting tolerance direction in limits-and-fits questions.
- Skipping safety sequence: isolate, lock out, then maintain.
