When you are working on your supervision hours, it may go a little something like this:
3,000 translate into approximately 2 years and if you look at any licensure requirements i think it will blatantly state both those figures (at least in the MD/DC area it does). You will not be followed daily at all. The person who provides your supervision will most likely NOT be your supervisor. You will perform your regular job duties wherever you work. I can't quite remember if it is an hour a day or a certain amount of hours/week. But that is how it goes and you will document the hours, almost like a timesheet. You might find someone within your job who is willing to provide the supervision. Or you might find someone outside of your job. A lot of times, if you find someone outside of your job, you may have to pay.
The purpose of meeting with the person providing supervision is to ensure that your work with clients, your mind and your process is on the right track. This is different than your work supervisor. Your supervisor reviews your specific work and has to ensure that your work follows the rules, policies and requirements of the job. The person who provides your supervision is specifically working with you around the clinical social work process; drawing from your work.
It is a little something like that. I have not gone through supervision because i do not want a clinical license. I have an MSW and am about to get my LGSW (kind of by force; even though it is helpful to have it). But i am very familiar with this as i just finished grad school in 2009, and many people I graduated with have or will be going through the supervision process.
And what Amerae said about the bilingual thing is absolutely correct. There are some jobs where it's necessary... period. So if they state it, they mean it.
I hope this helps.
