DRAUGHTSMAN MECHANICAL Assessment Criteria
The Draughtsman Mechanical trade under the Craftsmen Training Scheme (CTS) follows a structured assessment system designed to evaluate the technical knowledge, practical skills, and professional competencies of trainees. Assessment criteria are developed based on the learning outcomes defined in the curriculum and ensure that trainees acquire the necessary abilities to perform mechanical drafting tasks accurately and efficiently in industrial environments. :contentReference[oaicite:1]{index=1}
The assessment framework focuses on evaluating trainees’ abilities in engineering drawing, computer-aided drafting (CAD), interpretation of mechanical components, and preparation of production drawings. Both continuous internal evaluation and final examinations are conducted to measure the overall performance and competency of trainees throughout the training program.
Purpose of Assessment Criteria
The main objective of the assessment criteria is to verify whether trainees have achieved the competencies required in the Draughtsman Mechanical trade. Assessment ensures that trainees can apply theoretical knowledge in practical situations and demonstrate their ability to produce accurate engineering drawings.
It also helps instructors evaluate the progress of trainees during the training period and identify areas where additional guidance may be required. The assessment system ensures that training institutes maintain uniform evaluation standards across all Industrial Training Institutes (ITIs) in India.
Key Areas of Assessment
The Draughtsman Mechanical training program evaluates trainees in several important areas of mechanical drafting and engineering drawing. These areas include:
- Preparation of geometrical figures and basic engineering drawings.
- Orthographic projection drawing and dimensioning techniques.
- Freehand sketching of mechanical components.
- Construction of different types of engineering scales.
- Preparation of sectional views and development of surfaces.
- Drawing of fasteners, locking devices, gears, couplings, and bearings.
- Isometric and oblique projection drawing.
- Computer-aided drafting (CAD) and digital drawing preparation.
- Preparation of detailed and assembly drawings of machine parts.
- Three-dimensional modeling and visualization using CAD tools.
- Preparation of machine shop layout drawings.
- Production drawing preparation using CAD software.
- Interpretation of engineering drawings and technical specifications.
Each of these competencies is evaluated through practical assignments, theoretical examinations, and demonstration of drafting skills.
Continuous Internal Assessment
During the training period, trainees are evaluated through continuous internal assessment, also known as formative assessment. This evaluation method allows instructors to monitor the progress of trainees and provide regular feedback to improve their performance.
Training institutes maintain individual portfolios for each trainee. These portfolios contain records of assignments, practical work, attendance, project reports, and other evidence of skill development.
The evidence used for internal assessment may include:
- Practical work performed during drafting exercises.
- Record books and daily training diaries.
- Answer sheets from internal tests and quizzes.
- Viva-voce or oral examinations.
- Project assignments and CAD drawing files.
- Progress charts and performance reports.
- Computer-based multiple-choice examinations.
- Attendance and punctuality records.
These records are maintained until the final examination and may be verified by examiners during the certification process.
Final Assessment
At the end of the training program, trainees appear for the All India Trade Test (AITT), which is conducted by the Controller of Examinations under the Directorate General of Training.
This examination serves as the summative assessment of the training program and evaluates the overall knowledge and practical skills acquired by trainees during the course.
The final assessment consists of both theoretical and practical examinations. The question papers and practical assignments are prepared according to the learning outcomes and assessment criteria specified in the curriculum.
During the final evaluation, examiners may also review the trainee’s portfolio and performance records before awarding marks for practical work and project activities.
Pass Regulations
To successfully complete the Draughtsman Mechanical course, trainees must meet the minimum pass criteria established by the Directorate General of Training.
The minimum pass percentage for Trade Practical and Formative Assessment is 60%, while the minimum pass percentage for other subjects such as Trade Theory and Employability Skills is 33%.
For two-year courses, equal weightage is given to the examinations conducted during each year of training when calculating the final result.
Trainees who successfully meet the pass criteria are awarded the National Trade Certificate (NTC), which certifies their competence as mechanical draughtsmen.
Assessment Guidelines
While conducting assessments, training institutes must ensure that the evaluation process is fair, transparent, and unbiased. The assessment system should allow trainees to demonstrate their skills without creating unnecessary barriers.
Special attention should be given to trainees with special needs to ensure that they can participate effectively in the evaluation process.
The evaluation also considers factors such as teamwork, problem-solving ability, efficient use of materials, and adherence to safety procedures. Trainees are encouraged to minimize wastage and maintain environmental responsibility during practical training activities.
Performance Levels
Assessment results are categorized into different performance levels based on the marks obtained by trainees. These levels indicate the degree of competency achieved by trainees during the training program.
Performance Level: 60% – 75%
Trainees in this category demonstrate acceptable drafting skills and understanding of engineering drawing principles with occasional guidance from instructors.
- Shows reasonable proficiency in using drawing instruments.
- Maintains approximately 60–70% accuracy in practical drawing tasks.
- Produces drawings with acceptable quality and presentation.
- Requires occasional support while completing assignments.
Performance Level: 75% – 90%
Trainees in this category demonstrate strong drafting abilities and technical understanding with minimal guidance.
- Shows good proficiency in manual drafting and CAD applications.
- Maintains approximately 70–80% accuracy in drawing preparation.
- Produces clear and well-dimensioned drawings.
- Requires minimal supervision during project work.
Performance Level: Above 90%
This level represents excellent performance and advanced drafting skills. Trainees in this category demonstrate a high level of accuracy and professionalism in preparing engineering drawings.
- Demonstrates advanced proficiency in CAD and drafting techniques.
- Maintains more than 80% accuracy in drawing preparation.
- Produces high-quality technical drawings with detailed specifications.
- Completes projects independently with minimal guidance.
Importance of Assessment in Vocational Training
Assessment plays a crucial role in ensuring the quality of vocational training programs. By regularly evaluating trainees, instructors can identify areas where improvement is needed and provide appropriate guidance.
The structured assessment system also ensures that certified candidates possess the technical competencies required to work as professional draughtsmen in mechanical engineering and manufacturing industries.
Conclusion
The assessment criteria for the Draughtsman Mechanical trade provide a comprehensive framework for evaluating trainees’ technical knowledge, drafting skills, and professional behavior. Through continuous internal evaluation and final examinations, the training program ensures that trainees develop the competencies required for successful careers in mechanical drafting and design.
By maintaining high evaluation standards, the Draughtsman Mechanical training program contributes to the development of skilled manpower for the engineering and manufacturing sectors.
