This article addresses the Supreme Court's 2003 decision in "Lawrence v. Texas" and its implications for the rights of gay and lesbian public school teachers. The authors provide a context by reviewing the teacher role-model theory, traditional standards used in dismissals for immoral conduct, and pre-"Lawrence" cases regarding public employees' privacy rights. Then they analyze "Lawrence v. Texas", which struck down a Texas law imposing criminal penalties for persons of the same sex engaging in certain sexual conduct. The final section explores implications of the expanded liberty right announced in "Lawrence" for public school teachers and their lifestyle choices. (Contains 2 notes.)
