In some cases you might need to grade additional levels until you find the Instructional Level (a Green box followed by a Purple box)
In the example, the teacher assigned Level K to all students.
Rose mastered Level K and Level M, but she didn't master Level P. Her independent writing level is M, and her instructional level is P.
Daniel didn't master Level K or Level H, and he mastered Level E. His independent writing level is E, and his instructional level is H.
