Framework for Assessment Design. Assessment 
designers should start with the Standards for Educa-
tional and Psychological Testing, the book that describes 
industry standards for assessment development and val-
idation.
13
The Standards provides guidance for devel-
oping and evaluating assessments and outline the types 
of evidence needed to support valid inferences about 
assessment results. Basically, an assessment is valid if 
there is appropriate evidence to support the intended 
score interpretations and the ways in which those who 
give the test will use it. Validity is obviously crucial for 
assessment development in CBE programs, where test 
scores may be used to confer not only course credits but 
also degrees or certificates.
14
Imagine a test developed to measure a student’s 
knowledge of public-health laws, regulations, and 
policies. Students with higher scores should exhibit a 
greater level of knowledge of public-health concepts. 
Their level of knowledge, as evidenced by their test 
scores, could be used to determine whether they are 
awarded competency credits in this area and, by exten-
sion, whether they are prepared for future endeavors in 
public health. 
Although this understanding of test scores may 
seem intuitive, the ability to make valid inferences 
from assessment results relies on these simple axioms. 
For example, can the test developers demonstrate that 
knowledge of public-health laws, regulations, and 
policies—and not some irrelevant trait—explains test-
score variability? Moreover, do higher scores relate to 
higher levels of subsequent job performance? Valida-
tion is the process of accumulating evidence to answer 
these fundamental questions. According to the Stan-
dards, validity evidence can come from five sources: (1) 
test content, (2) response processes, (3) internal test 
structure, (4) relations to other variables, and (5) test 
consequences.
15
The first three sources of evidence generally reflect 
the test instrument itself, whereas the second two rely 
on data external to the assessment. Although not all 
sources of validity evidence may be present for every 
assessment, programs can make a strong validity argu-
ment by integrating evidence from multiple sources. 
For example, it is important to show that a competency- 
based assessment does test the knowledge and skills 
associated with the specified competency (evidence
