The National Teacher Recruitment Clearinghouse  lists links to state department of education Web sites (many of which list available teaching positions within the state), as well as teacher job-bank Web sites. The site also has other excellent info, such as an introduction to the teaching profession and a summary of licensure requirements. This one's a must-read.
Section 207 in Title II  of the Higher Education Act, as amended, requires each state receiving funding under the act to report annually on the quality of teacher preparation in the state, including
Requirements for an initial teaching certificate or license through either an alternate or regular route
Pass rates on each assessment used by states in certifying or licensing teachers
Teachers in the classroom on waivers, that is, teaching without an initial regular certificate or license from any state
State efforts in the past year to improve the quality of teaching.
Much of this information will be useful if you're considering a move into teaching. Of particular interest are this  list of state-level contacts for information on certification requirements and alternative certification programs, and this list of Web sites  for state teacher-certification offices.
The National Center for Education Information (NCEI) is an organization that advocates the expansion of alternative certification programs and the reduction of what it sees as artificial barriers to entry into the teaching profession. You'll find a list of state-by-state contacts for alternative certification information at their Web site .
Don't know how much longer this link will work for free, but for now you can get a list of reciprocal teacher licensure agreements  from the National Association of State Directors of Teacher Education and Certification (NASDTEC). Most of NASDTEC's  content now requires a paid membership ($25 annually). We didn't pay it, so we don't know how useful it is. But for now the above link still works (although the graphics don't).

Engaging Students: Teaching Scholar Partnerships The American Association of Community Colleges, in partnership with the Council of Independent Colleges and the Independent Colleges Office, developed the Teaching Scholar Partnerships  (TSP) project in 2001 with support from the National Science Foundation. TSP brings together 2- and 4-year institutions seeking solutions to the shortage of qualified science and math educators in elementary, middle, and secondary schools. Through grant competitions, review teams for the three national organizations selected 10 community colleges and 18 4-year colleges and universities located in diverse settings in 17 states to participate in a pilot project. Their involvement as TSP Colleges comes with 2-year implementation grants of $30,000 each. TSP objectives are to enrich and strengthen the learning experience of K-12 students in mathematics and science by encouraging undergraduate students in science, technology, engineering, and mathematics to consider K-12 math and science teaching as a career option.
