ln the Civil Service, workers without formal education but are trained in different fields to perform mainly menial services are referred to as ....... class.

Step 1: Analyze the question The question asks which Civil Service class is made up of workers who have no formal education, are trained in different fields, and perform mainly menial (low-skilled, manual) services.

Step 2: Explain the concept The Nigerian Civil Service is divided into broad classes:

• Administrative class: top-level policy advisers and managers (Permanent Secretaries, Directors). They are university graduates.
• Professional/Specialist class: people with specialized qualifications such as doctors, engineers, and lawyers.
• Technical/Executive class: people with technical or secondary and post-secondary training who supervise and carry out technical or executive work.
• Clerical class: people with secondary school education who handle records, typing, filing, and routine office work.
• Auxiliary (sub-clerical/manipulative) class: workers with little or no formal education who do simple, menial jobs such as messengers, cleaners, gardeners, drivers, and gatekeepers.

Step 3: Match the description "Without formal education" and "menial services" point to the lowest level of the service. The clerical class requires some formal education, so it does not fit. The administrative, specialist, and technical classes all require advanced education or training. The class that fits is the auxiliary class.

Step 4: Answer The correct option is B. auxiliary.

Tip: Think of "auxiliary" as "assistant or support." Auxiliary staff support everyone else through basic tasks. Also remember the ladder of education: Administrative (highest) → Professional/Specialist → Technical/Executive → Clerical → Auxiliary (lowest).
