Some clients may also require a drug test or an additional background check at no extra cost to you. If the client requires this, it will be outlined in the announcement on the portal and must be completed prior to the first day of class. *Important drug test information – please do not drink a lot of water prior to your test or your results may come back as “negative dilute” which means you have to retake it. Also note that if the client requires a drug test, please take it as soon as you possibly can. If you wait until the last minute you may not get course access and fall behind.
