which of the following is a recruitment source

a college job fair
a job applicant
a high school diploma
a job reference

The correct answer is: a college job fair.

A college job fair and a job applicant are both recruitment sources. A college job fair is an event where employers have the opportunity to meet and recruit potential candidates from college campuses. A job applicant is an individual who submits an application for a job position, either directly to the company or through a job portal or recruitment website.

However, a high school diploma and a job reference are not recruitment sources. A high school diploma is an educational qualification, while a job reference is a person who can vouch for an applicant's qualifications and abilities. These are not sources from which recruitment takes place.

The recruitment source among the options you provided is a college job fair.

To better understand how to determine which option is the correct answer, let's briefly go through each option:

- A college job fair: This is a recruitment source as it is an event where employers set up booths or tables to meet and recruit potential candidates from college campuses.

- A job applicant: While a job applicant is not typically considered a recruitment source, they are individuals who apply for a job and are part of the hiring process. They can be considered as candidates for potential employment.

- A high school diploma: A high school diploma is not a recruitment source. It is an educational qualification that may be required for certain jobs, but it does not directly contribute to the recruitment process.

- A job reference: A job reference is not a recruitment source either. It is a person who can provide information about an applicant's work experience, skills, and character to assist in the hiring process.

So, given the options provided, the correct answer is a college job fair, as it is an event specifically designed for recruitment by employers on college campuses.
