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
