Pdf Icon NAS Classroom Agenda (as of 9/3/19)


Student Prework  

This prework is extensive and requires a serious amount of time on your part before you arrive at the School. Don’t plan on completing the prework while you are at the School or you will find yourself falling behind. The volume of material can be overwhelming if you are not prepared. We suggest beginning the prework several weeks before the classroom session. You’ll not only benefit more from the learning opportunities at the School, you’ll enjoy your experience more.
