Final answer:
Except for checking employment references, activities like providing training, supporting education, and performing evaluations are all components of personnel development control plans. Checking references is a pre-employment activity rather than an ongoing development process.
Step-by-step explanation:
Personnel development control plans are mechanisms to ensure that employees not only fit into the organizational culture but also grow and contribute effectively over time. In the context of the question, all of the options listed except for checking employment references are typically part of such plans. These options—providing sufficient and timely training, supporting employee educational interests, and performing scheduled evaluations—are directly related to the development and control of personnel performance and growth within a company. Checking employment references is generally part of the initial hiring process rather than personnel development.
Ensuring sufficient and timely training helps employees acquire necessary skills and knowledge, which can positively influence productivity and job satisfaction. Supporting educational pursuits aligns with employees' personal growth and can lead to enhanced career opportunities. Systematic evaluations allow both the employer and employee to understand strengths, areas for improvement, and the effectiveness of training programs, offering a platform for ongoing feedback and development.
