It's extremely hit or miss. Some schools do and some schools don't. High schools are supposed to include it in the required health class, but that class isn't a state tested subject, so it's often taught by long-term subs or other unqualified individuals. It's often glossed over or taught ineffectively. The adults teaching the class don't have a thorough required training for the subject matter so the quality varies dramatically.

Sex ed is not required in middle school. Some schools will provide it, particularly as part of a partnership program with Planned Parenthood, Hopkins, or something like that. But many schools do not provide it at all. At the middle school level, it depends on if it's a priority of the school administrators.
