    With a handful of years in the EHS realm, the OHST was a barometer of my knowledge... There are a number of areas that I found I needed to study up on. The Exam Prep offered through SPAN helped pinpoint where I had to focus my efforts.

    I studied off and on for a year and finally and was able to pass on my first go around.

    I believe this tool worked for the way I study and would use it again for future certifications (onto CIH now)...
