Many school districts in Texas now place their vacancy announcements on the World Wide Web. The gopher menu for this service will let you look for jobs in Texas or post your resume. Also, you will want to visit the Texas Education Agency's website in order to research individual districts via annual performance reports. A terrific, comprehensive, award winning site for links to organizations, journals, and institutional webpages that post positions in higher education. Chronicle of Higher Education subscribers get the first peek at jobs on Fridays, non-subscribers can see jobs the following week.
Positions range from research assistants to tenured faculty to chancellors are here.
Hard copies are available for your perusal in the Undergraduate Library. Another good site, but you must either be a member of an affiliated student group or an individual member to access their job postings. For membership information, go to the site. Their job search site includes postings from schools actively seeking women to fill their job vacancies. They also include fellowship information for women.
