Is it okay to put that I was president of my technological high school back in 2008 on my job resume?

Only if you were the actual president of the school - do you mean principal of the school? Okay, so what club were you the president of, and is it a strong enough position to be noteworthy? Do you have little or no experience since 2008? If you have at least three job experiences, only include this if it seems as strong or a stronger point of interest to an employer than what your job positions have been ----------------------
