• This year's seventh-graders (regular or advanced) will be working on the Districts Essential Outcomes for 7th and 8th grade.  We enhance in as many areas as we can to provide a deeper and more concrete understanding of the materials.  Please also remember that there is overlap on many of the topics which strengthen the knowledge base.  If you have further questions about these Outcomes, please call and chat.
