Which practice is NOT allowed for individuals who lack a proper license?

The practice that is not allowed for individuals who lack a proper license includes conducting therapy sessions, providing psychological assessments, and utilizing the title 'psychologist'. In the field of psychology, licensure is a regulatory measure that ensures practitioners have met specific educational and training requirements to competently provide psychological services.

Conducting therapy sessions without a license can lead to serious ethical and legal ramifications, as unlicensed individuals may not have the necessary skills to guide clients effectively through mental health challenges. Similarly, psychological assessments require a deep understanding of psychometric principles and ethical considerations, making it critical for only licensed professionals to administer and interpret these assessments correctly.

Additionally, the use of the title 'psychologist' is legally restricted to those who have obtained the proper licensure. Misrepresenting oneself as a psychologist without the appropriate credentials can mislead clients and undermine public trust in the psychological profession.

Given these reasons, it is clear that all the practices listed are prohibited for unlicensed individuals, which affirms that the correct answer is that none of these actions are allowed.
