Surveyor Assessment Criteria
The Assessment Criteria for the Surveyor trade under the Craftsmen Training Scheme (CTS) defines the standards used to evaluate the performance, technical knowledge, and practical skills of trainees during the course. These criteria ensure that students are able to demonstrate the required competencies before completing their training and receiving the National Trade Certificate (NTC).
The assessment system is designed to evaluate a trainee’s ability to perform surveying tasks accurately and safely. It measures both theoretical understanding and practical capabilities. Assessment is based on the learning outcomes defined in the course curriculum and is conducted through practical demonstrations, written examinations, assignments, and project work.
Purpose of Assessment Criteria
The main purpose of assessment criteria is to verify that trainees have acquired the skills required to perform surveying activities in real engineering and construction environments. The evaluation process ensures that trainees can correctly use surveying instruments, interpret technical drawings, conduct field surveys, and prepare accurate maps and reports.
Assessment criteria also help training institutes maintain uniform standards of vocational education across the country. By following these criteria, Industrial Training Institutes (ITIs) can ensure that all trainees meet the same level of competence before entering the workforce.
Assessment Based on Learning Outcomes
The Surveyor trade assessment is closely linked to the learning outcomes defined in the curriculum. Each learning outcome describes a specific skill or competency that trainees must demonstrate. The assessment criteria describe how these outcomes will be evaluated during training and final examinations.
For example, trainees must demonstrate their ability to prepare drawing layouts, perform site surveys, operate surveying instruments, and process measurement data. They must also show proficiency in using computer software such as AutoCAD for preparing survey drawings and technical plans.
Assessment Criteria for Basic Drawing Skills
One of the first competencies evaluated in the Surveyor course is the ability to perform basic engineering drawing tasks. Trainees must be able to prepare drawing sheets, create title boxes, and organize layouts according to standard engineering drawing practices.
Students are assessed on their ability to draw horizontal lines, vertical lines, parallel lines, and various types of lettering using drawing instruments such as T-squares and set squares. They must also demonstrate knowledge of dimensioning methods and drawing conventions used in surveying.
The ability to construct geometrical figures, curves, and conic sections is also assessed. These exercises help evaluate a trainee’s understanding of geometry and drawing accuracy.
Assessment Criteria for Scale and Map Symbols
Another important part of the assessment process is the ability to construct different types of scales used in surveying drawings. Trainees must demonstrate their ability to calculate the representative fraction (R.F.) and draw scales such as plain scales, diagonal scales, and vernier scales.
Students must also demonstrate knowledge of conventional signs and symbols used in topographical maps. These symbols represent physical features such as roads, rivers, buildings, and vegetation, and they help communicate geographical information clearly in survey drawings.
Assessment of Field Survey Skills
Practical surveying skills form the core of the assessment process. Trainees must demonstrate their ability to perform field surveys using different instruments and techniques.
For chain surveying, trainees are evaluated on their ability to measure distances using chains or tapes, take offsets, record measurements in field books, and prepare site plans. They must also show understanding of errors that occur during chaining and methods used to correct them.
Compass surveying skills are also assessed. Students must measure bearings of lines, conduct traverse surveys, compute correct bearings, and adjust closing errors in traverse calculations.
Assessment of Instrument Handling
Handling and operating surveying instruments is a key competency that trainees must demonstrate during assessment. They must show the ability to set up instruments correctly, perform temporary adjustments, and take accurate measurements.
For example, trainees are evaluated on their ability to set up a plane table, perform radiation and intersection methods, and prepare field sketches during plane table surveys.
Similarly, when performing theodolite surveys, students must demonstrate the ability to measure horizontal and vertical angles, determine heights of objects, and conduct traverse surveys.
Assessment of Levelling and Height Determination
Levelling is another essential surveying skill evaluated during training. Trainees must demonstrate the ability to set up leveling instruments such as dumpy levels or auto levels and determine reduced levels of different points.
Students are also assessed on their ability to perform different types of levelling such as differential levelling and reciprocal levelling. They must be able to record observations in level books and calculate reduced levels using standard methods.
Assessment of Survey Projects
The assessment process also includes evaluating trainees on real-world surveying projects. These projects may include road surveys, preparing longitudinal and cross sections, and calculating earthwork volumes.
Students must demonstrate their ability to apply surveying techniques in practical situations and prepare professional survey drawings based on collected data.
Assessment of Computer-Aided Survey Drawing
Modern surveying requires knowledge of computer-aided design. Therefore, trainees are also assessed on their ability to create drawings using AutoCAD software.
Students must demonstrate their ability to use CAD commands to prepare site plans, survey traverse drawings, and building layouts. This skill ensures that trainees are prepared to work with modern digital surveying technologies.
Evaluation of Accuracy and Professional Skills
In addition to technical knowledge, the assessment criteria also evaluate the accuracy, precision, and quality of work produced by trainees. Students must demonstrate good craftsmanship, attention to detail, and adherence to safety procedures.
They are also assessed on their ability to work independently, solve problems during survey operations, and maintain proper documentation of measurements and calculations.
Conclusion
The assessment criteria for the Surveyor trade play an important role in ensuring that trainees achieve the required level of competence in surveying skills. Through continuous evaluation and practical examinations, training institutes verify that students can perform professional surveying tasks accurately and efficiently.
By meeting these assessment standards, trainees become capable of working in fields such as civil engineering, construction, land development, and infrastructure planning. The structured assessment system ensures that graduates of the Surveyor trade are well prepared to contribute effectively to engineering and surveying projects.
