Use the information below to answer questions 20 and 21.

The Missouri Assessment Program (MAP) consists of a number of tests designed to assessstudent mastery of the Missouri Education Show-Me Standards. Although the MAP measuresstudents' knowledge and how practically and effectively they can apply it to tasks in theclassroom and in the real world, the MAP is also used to initiate educational reform and to helpeducators in Missouri evaluate the curriculum and instruction of their content area (if theircurriculum is in accordance with the Show Me Standards).

The MAP is administered in Missouri schools at different grade levels. It begins at grade 3 and isadministered every year through grade 11. Each year different subject areas are administered.For example, 3rd and 7th graders take science and communication arts, while 4th and 8th graderstake math and social studies. Each subject area assessment consists of three parts:

A. Multiple Choice using the Terra Nova Survey, where students are given 5 choices to choosefrom on each question. The Terra Nova is used so educators can compare the performance oftheir students with others nationwide. This is the only timed section of the test.

B. Constructed Response, where students give their own response to each question. Students areusually required to show work.

C. Performance Event, where students draft a more lengthy response to a prompt. This section isused to assess students' ability to apply knowledge to everyday situations.

20. If you wanted to establish that the MAP is a reliable measure, which types of reliabilitywould it make sense to examine? How would you go about gathering these types ofreliability (what statistics would you use)?
