PREFACE

Tharanga Naleen Gamlath R. D. S. Kumararatne Chairman Director General National Apprentice & Industrial Training Tertiary & Vocational Education Authority Commission

National Competency Standards (NCS) and curriculum are an essential element for the

implementation of a unified Technical and Vocational Education & Training System for Sri Lanka

and forms the basis for the National Vocational Qualification Framework of Sri Lanka, which

provides for the award of nationally and internationally recognized qualifications. The NCS are

developed in consultation with industry and are designed using a nationally agreed specific

format to maintain uniformity and consistency of standards amongst occupations.

The NCS specify the standards of performance of a competent worker and the various contexts

in which work may take place. NCS also describe the knowledge, skills and attitudes required

in a particular occupation. NCS and curriculum provide explicit advice to assessors and

employers regarding the knowledge, skills and attitudes to be demonstrated by the candidates

seeking formal recognition for the competencies acquired either following training or through

work experience.

NCS focus on what is expected of a worker in the workplace and the curriculum focus the

learning process.

• NCS stress upon the ability to transfer and apply knowledge and skills to new situations and environments.

• In NCS and curriculum the emphasis is upon outcomes and upon the application of knowledge and skills, not just the specification of knowledge and skills.

• NCS and curriculum are concerned with what people are able to do and the ability to do a task in a range of contexts.

• NCS and curriculum include all aspects of workplace performance and not only narrow task skills. NCS can serve a number of purposes including: o Providing advice to curriculum developers about the knowledge, skills and

attitudes to be included in the curriculum.

o Providing specifications to Competency Based Assessors about the knowledge,

skills and attitudes to be demonstrated by candidates.

o Providing advice to industry about job functions, which in turn can be used for the

development of job descriptions, performance appraisal systems and work flow

analysis.

The lead organization for the development of NCS and curriculum is the National Apprentice &

Industrial Training Authority. The standards so developed are endorsed by the Tertiary &

Vocational Education Commission as National Documents.

There is a requirement to review the standards within the prescribed period as appropriate as

and when required, with the assistance of relevant industry groups and incorporate the

changes in the National Competency Standards

Assessment Guide:

Forms of assessment

Assessment shall be based on evidence collected through workplace performance or a

combination of evidence collected through training and work place performance.

Assessment context

This unit may be assessed on the job, off the job or a combination of on and off the job. The

unit may be assessed individually.

Assessment conditions

The candidate will have access to:

- all tools, equipment, material and documentation required.

The candidate will be permitted to refer the following documents:

- material, paint and polish safety data sheets

- health and safety regulations

- product data sheet (PDS)

- company specification sheets

- manufacturer’s instructional brochures and manuals

The candidate will be required to:

- orally or by other methods of communication, answer questions asked by the

assessor.

- identify superiors and clients who can be approached for the collection of

competency evidence where appropriate.

- present evidence of credit for any off job training related to this unit.

Assessors must be satisfied that the candidate can competently and consistently perform all

elements of the unit as specified by the criteria and that he/she possess the required

underpinning knowledge.

Special notes

During assessment, the candidate will;

demonstrate safe work practices at all times

communicate information about processes, events or tasks being undertaken to

ensure a safe and efficient working environment.

perform all tasks in accordance with standard operating procedures.

perform all tasks to specifications

take responsibility for the accuracy of his/her own work

use accepted methods for calculation.


74

Tasks involved will be completed within reasonable time frames relating to typical workplace

activities.

Resources required for assessment

These include material, tools and equipment listed within this unit
