Unfortunately, I only have one placement that will last into May. I think in my neck of the woods, it depends both on the college and also on major, like Ima Teacher mentioned. People who get certified in the older grades, major in 2 subject areas (e.g. math and science), so they do two placements. Some colleges do a year long in the same placement, but the first semester isn't full-time and considered field practicum hours, while the 2nd semester in the same placement is labeled student teaching and is full-time.
