Which of the following is a requirement for maintaining a real estate license in Indiana?

In Indiana, maintaining a real estate license does require the completion of continuing education credits. This requirement is in place to ensure that real estate professionals stay abreast of current laws, regulations, and best practices in the industry. Continuing education helps licensees refresh their knowledge and adapt to changes that may affect their practices, thereby promoting professionalism and competency within the field.

The other options do not accurately reflect the requirements for maintaining a real estate license in Indiana. For instance, stating that there are no ongoing requirements would be incorrect, as continuing education is mandated. Similarly, a one-time fee does not address the necessity for ongoing education, and while there's no minimum number of properties that must be sold annually to maintain a license, licensees must engage in educational activities consistently throughout their license period.
