Each type of assessment used in the School District of Clayton measures student growth and achievement in a slightly different way, supplying the District with a more complete picture of a student's learning profile than any one of them could alone.
One assessment used to collect data regarding student growth in mathematics is Northwest Evaluation Association's (NWEA) Measure of Academic Progress (MAP). This growth assessment is given three times a year to all elementary students and two to three times a year to all middle school students. The purpose of this assessment is to provide teachers with reliable, instructionally useful data, which can be used to identify each student’s optimal learning path and monitor student progress over time.
One Data Point
Similar to other assessments your child participates in, this is one piece of data that makes up their complete data profile. It is important to understand that the NWEA MAP is one test at one point in time and does not measure intelligence or a student’s capacity for learning. When making important decisions about students, the NWEA MAP test is only one piece of data that is considered.
Unlike the Missouri MAP assessment, which is a fixed form assessment, the NWEA MAP assessment is computer adaptive. This means that the difficulty of each question is based on the student’s answers on previous questions. A correct answer will lead to a more difficult question, and an incorrect answer will lead to an easier question but more difficult than the last correctly answered question. The assessment takes approximately 30 minutes for second-fifth-graders and 60 minutes for sixth-eighth-graders and uses approximately 50 questions to determine a student’s score called a RIT. RIT stands for Rausch Unit. The RIT scale is and equal-interval measurement scale (much like feet and inches on a yard stick) independent of a student's grade or age. Each RIT score falls in a 10 points RIT band that relates directly to learning objectives.
RIT Reference Chart:
The RIT Reference Chart is helpful for understanding the RIT scale and how it is used to measure student growth over time in relationship to math concepts. For more specific information about the learning statements within each RIT band, you can reference the DesCartes Learning Continuum Statements below.
DesCartes Learning Continuum Statements:
Using Learning Continuum statements you can see what students performing at a given RIT level are typically ready to learn. Learning statements for a RIT band are divided into three columns. The lefthand column includes skills and concepts related to questions your child answered correctly 73 percent of the time. These are skills and concepts students may need reinforced to build consistent proficiency and confidence. The middle column includes skills and concepts related to questions your child answered correctly 50 percent of the time. These are skills and concepts your child is ready to learn. The column on the right includes skills and concepts related to questions your child answered correctly 27 percent of the time. These are skills and concepts in which your child may be ready to be introduced. To use the Learning Continuum, reference the page that shows the RIT band in which your child's score fell for each subject area. For example, if your child is in fourth grade and his/her RIT Range for the goal performance area of Geometry is 216-228, you would open the Geometry document below under Grades 2-5 and turn to the page where the RIT band 211-220 or 221-230 is in the center column.
