Yes, you read the title right, that’s the name of this new standard for kids: K, as in Kindergarten, to 12th grade.
“The National Sexuality Education Standards were further informed by the work of the CDC’s Health Education Curriculum Analysis Tool (HECAT); existing state and international education standards that include sexual health content; the Guidelines for Comprehensive Sexuality Education: Kindergarten – 12th Grade; and the Common Core State Standards for English Language Arts and Mathematics5, recently adopted by most states.”

I am not in MN but am a teacher in another state. I would like to see where you are getting your info. I am not expressing my views either way on CCSS on public forums due to the nature of my job but I am reading what friends of mine post. I saw this one recently and with this being the first I have heard of it and since I can’t find any info regarding it- I would like to know where you are seeing this.
Hello Tami
Thank you for writing in. I have been a teacher for 25 years. I’m not exactly sure about your question? Are you asking specifically about the National Sexuality Standards or about Common Core SS? Government websites, federal and state, document all of the information about educational programming and the implementation of such. That is where we find most of our information. Perhaps you could restate your question and I’ll be happy to answer.
I want to know what your source is for this info. Neither I, nor other teacher friends, have ever heard of National Sexuality Standards.
It’s sitting on the internet. If I was still teaching, I would never have the time track all this down. I’ll go find the link. These standards are known as “O”s standards, developed with stakeholders like Planned Parenthood, etc., etc. Be back!

These have been out for a number of months that I am aware. They are now aligned to Common Core, which only means that they are now tied into the system.
