Report Card InformationWe know there are always questions about your child's progress and how that progress is measured. Below are links explaining this process in DVUSD. The biggest area of concern is usually how your child's mastery of the standards is measured. The standards are measured on a scale of one to four. Grade level mastery is a level three. This level is where most, if not all, students will be. Level four mastery is designated for those students who consistently and independently work one year above grade level.
