ExploreAbout this exam
The ITI/NCVT Painter General All India Trade Test (AITT) is the theory examination sat by trainees completing the Painter General trade under the Craftsman Training Scheme. It tests trade theory - the knowledge behind surface preparation, paint composition, application, spray work, decorative finishes, fault diagnosis, colour matching, protective coatings and estimation - rather than workshop skill, which is assessed separately in practical and allied trade tests. Candidates are typically ITI trainees nearing the end of their course, but anyone revising the trade syllabus for a refresher or employment test will find the same content useful.
The paper is objective and multiple choice, delivered in the language of instruction, and is drawn from the trade theory syllabus rather than from a single textbook. Because questions reward precise vocabulary - the difference between a primer and a sealer, between orange peel and sagging, between a drier and a thinner - preparation should be built around definitions and cause-and-effect reasoning, not memorised lists.
A sound plan: work through the syllabus domain by domain, keep a notebook of terms with one-line explanations, and practise explaining each defect's cause and remedy aloud. Study safety and surface preparation first, since almost every later topic assumes them. Confirm the current question count, duration, passing marks and certificate details with the official NCVT/DGT authority, as these are set by the scheme and change over time.

About ITI/NCVT Painter General (AITT Theory) preparation
What is the format of the Painter General AITT theory paper?
It is an objective, multiple-choice trade theory paper covering the Painter General syllabus. Questions are in the language of instruction and test recall plus applied reasoning about materials, methods and faults. The official NCVT/DGT authority publishes the current pattern and any updates, so check there rather than relying on older trainee accounts.
How long is the exam and how many questions are there?
Those figures are set by the AITT scheme and are revised from time to time, so no fixed number should be quoted. The current question count, duration and passing marks are published by the official NCVT/DGT body. Confirm them on the official site or through your institute before you plan your revision timetable.
How difficult is the theory paper?
Most candidates find it moderate: the concepts are practical rather than abstract, but the paper is precise about terminology. Marks are lost on small distinctions - primer versus undercoat, drying versus hardening, a defect's cause versus its remedy. If you can explain why each step is done, not just what it is called, you are usually well prepared.
Can I retake the exam if I fail?
Retake and supplementary examination arrangements are governed by the AITT scheme and differ by session and institute. The official NCVT/DGT authority publishes the current rules on reappearing, backlog papers and result processing. Ask your training institute's exam cell for the applicable procedure rather than assuming a fixed number of attempts.
In what order should I study the syllabus?
Start with safety and surface preparation, because every later topic depends on them. Then take paints and thinners, followed by application methods and spray equipment. Decorative finishes, defects, colour and protective coatings sit naturally after that. Finish with estimation and employability skills, which are lighter and easier to revise close to the exam.
What do candidates most often get wrong?
Common weak spots are mixing up defect causes and remedies, confusing the roles of primer, putty and finish coat, and misjudging thinner ratios and drying times. Spray faults - orange peel, runs, dry spray - are frequently muddled. Colour theory questions on complementary colours and tinting also catch people out. Practise explaining each in one clear sentence.
Do I need to memorise mixing ratios and drying times?
You should know typical ranges and the reasoning behind them, such as why a primer is thinned differently from a finish coat, or how temperature and humidity shift drying. Manufacturer data sheets give exact figures for specific products. Examiners usually test understanding of the principle rather than one brand's precise number.
How should I prepare in the final weeks?
Revise by domain, not by random questions. Write one-line definitions for every trade term you meet, then test yourself by covering the answers. Sketch defect diagrams and label causes and remedies. Time yourself on practice sets to build pace, and revisit safety and surface preparation last, since they appear throughout the paper.
Is the AITT theory paper the same as the practical test?
No. Theory, practical and allied trade subjects are assessed separately under the Craftsman Training Scheme. This paper covers trade theory only. Workshop skill, tool use and finished work quality are judged in the practical examination, so prepare for the two differently even though the underlying knowledge overlaps.
