What information must be documented for every employee in addition to qualifications?

The correct choice focuses on the necessary documentation related to employee qualifications in an assisted living facility. While qualifications themselves are crucial, it is equally important to verify that the training a new hire has completed is appropriately recognized, which is why the documentation of the training agency's board approval is required. This ensures that the training meets applicable regulatory standards and is deemed acceptable for practice in the assisted living environment.

Documentation of the training agency’s board approval not only reinforces the credibility of the employee's qualifications but also enhances compliance with state regulations that govern assisted living facilities. Such oversight is essential for maintaining high-quality care and upholding safety standards, which are paramount in the healthcare industry.

Other aspects like emergency contact information or performance reviews, while relevant for employee management, do not pertain directly to the qualification verification of the individual. Similarly, documenting prior work experience is beneficial but does not hold the same regulatory importance as confirming the recognition of training by an accredited board—making the latter the appropriate focus for qualifications-related documentation.
