Which of the following actions would be classified as subversion during the testing process?

Subversion during the testing process refers to any action intended to undermine the integrity of the testing procedure. In this context, all the actions listed—providing a sample from a colleague, attempting to dilute a specimen, and not reporting for testing—contribute to an effort to circumvent the personal accountability and honesty required for testing integrity.

Providing a sample from a colleague clearly indicates an attempt to substitute a personal specimen with someone else's sample, which disrupts the validity of the results. This act not only misrepresents the individual's status but also compromises the testing environment's integrity.

Attempting to dilute a specimen is another form of subversion. By trying to alter the concentration of substances in the sample, an individual seeks to manipulate the test outcomes, which may aid in concealing substance use or other issues.

Finally, not reporting for testing can equally be seen as a subversive act. By avoiding the testing process altogether, an individual sidesteps the possibility of a legitimate evaluation of their fitness, thereby raising questions about their compliance and willingness to be assessed.

Thus, all these actions are classified under subversion as they share the common goal of invalidating the testing process, which is why the correct answer encompasses all of the choices provided.
