Opportunity to Learn (OTL) Standards identify the resources that teachers, schools and districts need for all students to achieve at or above the levels suggested in the 2014 National Core Arts Standards. With the passage of the Every Student Succeeds Act (ESSA) and the widespread adoption or adaptation of the National Core Arts Standards across the United States, defining the resources required to achieve literacy in each arts discipline is especially important and timely. OTL Standards serve as a key component in the fair and reliable evaluation of arts educators and arts programs.
