"Currently there is no consortium work similar to the Essential Elements for social studies, therefore Wisconsin is starting the process to write alternate standards for social studies. The alternate standards are K-12 academic standards, are aligned with college and career expectations, include rigorous content, and application. For students to be college and career ready, including students with the most significant cognitive disabilities, educators should include instruction in both academic content, as well as the reading and writing skills needed to demonstrate learning in the other disciplinary areas."
