Relate curriculum to real-world problems rather than "school-world"
Achieve higher level thinking of Bloom's Taxonomy

Multiple Foci
The most significant concept in assessment
Content Validity: "refers to the adequacy with which the content of a test represents the content of the curricular aim about which inferences are to be made" (Chapter 4).
Criterion Validity: "this kind of evidence helps educators decide how much confidence can be placed in a score-based inference about a student’s status with respect to one or more curricular aims" (Chapter 4).
Aptitude Test
Construct-Related Validity: "is typically gathered by way of a series of studies, not one whopper 'it-settles-the-issue-once-and-for-all' investigation" (Chapter 4).
Validity
Developmental Care: the higher the stakes, the more effort given to content procedures ensure curricular aims are involved
External Reviews
Alignment
Aptitude Tests
Intervention Studies, Differential-Population Studies, Related-Measures Studies
Reliability
Correlation Coefficient
Classification Consistency
Item Response Theory
Include more items on educational assessment to yield more reliable estimates
Reliability = Consistency
Stability Reliability: "refers to consistency of test results over time" (Chapter 3).
Test-Retest Reliability
Alternate-Form Reliability: 'focuses on the consistency between two forms of a test—forms that are supposedly equivalent" (Chapter 3).
Internal Consistency Reliability: "does not focus on the consistency of students’ scores on a test. Rather, internal consistency deals with the extent to which the items in an educational assessment instrument are functioning in a consistent fashion" (Chapter 3).
