DesCartes / The Curriculum Connection

NWEA Knowledge Academy

Intended Accomplishments • Review • The RIT scale

• RIT scores and percentile rankings • Score ranges and goal scores • Learn to read and interpret different reports

• Use data to focus instruction • Overall RIT • Michigan Ver. III Goal performance • DesCartes Learning Continuum and Lexile • Develop a plan for using the data


Instructional Level • The NWEA test is not a test for determining mastery of skills. • It provides a road map for students toward achieving mastery.

This test provides the instructional level of the student. 3

Checkpoint! • How would you describe a RIT? • What does “equal interval” mean? • What are the major strengths of NWEA assessments?


Never use only one point of data

Triangulation MEAP / MME / ACT Teacher (Common Assessments, Dibels, DRA, Benchmarking, etc)


Placement Guidelines A RIT is only one piece of the puzzle for making important decisions.

What are expected RIT and growth scores?


What does the standard deviation tell us? Standard deviations (Std.Dev.) are indicators of the academic diversity of a group of students.

Sample Math Teacher Report p. 2 17

Larger standard deviations . . . • Indicate that the group is more diverse. • It is likely that small group instruction is more appropriate in these areas than whole group instruction.

Lower standard deviations ...  

Indicate that students are most alike in this area. Large/full group instruction may be appropriate. 18

Think about… Would we expect the standard deviation of a class to change from fall to spring?

Why or why not? 19

Scavenger Hunt Use your student’s data! • • • • •

Which student has the highest score? Which student has the lowest score? Which student has the median score? Which goal area has the highest mean? Which goal has the lowest standard deviation?


What does “Goal Performance” mean? • Goal scores are percentiles based on the entire group of students in the norming study at each student’s grade level. • They tell how a given student compares with others in this whole group. • For example, if a student is at the 70th percentile, it means that 70% of the students in that grade level scored lower than this student.


Goal Score Descriptors

Goal scores Scores • Hi = Percentile greater than 66 • Av = Percentile scores between 66 and 34

• Lo = Percentile scores less than 34 • Hi > 80 percentile

On Student• Progress • Reports • only

HiAvg = 61-80 percentile

Av = 41-60 percentile LoAvg = 21-40 percentile

• Lo < 21 percentiles 24
