Undergraduate - Choose this option if you do not have a college degree. You should declare biology as your major.

Post-graduate - If you already have an appropriate Bachelor 's degree in biology, you may wish to enroll as a post-graduate and just pursue teacher certification. Post-graduates are classified as undergraduate students. They may be pursuing a second bachelor's degree or simply be pursuing a teaching license. They do not have the ability to enroll in graduate level courses. Students often pursue this choice when they have a biology degree and need to take undergraduate level biology courses while pursing certification. It is possible to switch status from post-graduate to either student-at-large or graduate student. You can not switch back once you done so.

Student-at-Large - Choose this option if you have a bachelor's degree and wish to be able to take some courses for graduate credit. Students pursue this option when they are unsure of whether or not they wish to pursue a masters or if they don't have time to complete the lengthy application process for admission to a graduate program as a graduate student. It is always possible to switch status from student-at-large to graduate student.

Graduate student - A graduate student is someone who is pursuing a graduate degree, either masters or doctorate. It is not necessary to complete the degree to complete the teacher certification program in biology. The advantage of being either a graduate student or student-at-large is that graduate level courses taken toward a degree are used to move individuals on the salary schedule. In other words, you get paid more as a teacher, if you have more education. Some school districts only count coursework toward a degree in your teaching area.
