Which type of testing aims to ensure knowledge and skills for career certification?

Competency testing is specifically designed to evaluate whether an individual possesses the essential skills and knowledge required to meet the standards for certification in a particular career field. This type of testing focuses on assessing the practical abilities that demonstrate a candidate's readiness to perform job-related tasks effectively and safely.

In the context of CNA (Certified Nursing Assistant) training, competency tests typically include both written examinations and practical demonstrations of skills. This ensures that candidates not only have the theoretical knowledge needed to understand their responsibilities but also the hands-on skills required to provide patient care effectively.

The other types of testing mentioned do not primarily focus on certification. Diagnostic testing is used to identify areas of weakness or learning gaps, performance evaluations assess ongoing job performance rather than initial competency, and individual assessments can encompass a wide range of evaluations without specifically targeting career certification. Therefore, competency testing is the most relevant to ensuring that a candidate is prepared for certification in their career.
