These pieces represent a wide variety of content areas, curriculum units, conditions for writing, and purposes.  They reflect Common Core State Writing Standard 10, which specifies that students “[w]rite routinely over extended time frames (time for research, reflection, and revision) and shorter time frames (a single sitting or a day or two) for a range of tasks, purposes, and audiences.” 

Grades 11-12 student work can also be found in the "On-Demand" writing  selection, which shows the progression of writing from grades 6-12, when students are provided the same prompt across grade levels.
