Test : A method to determine a
student's ability to complete certain tasks or demonstrate mastery of a skill
or knowledge of content. Some types would be multiple choice tests, or a weekly
spelling test. While it is commonly used
interchangeably with assessment, or even evaluation, it can be distinguished by
the fact that a test is one form of an assessment.
Assessment : The process of gathering information to
monitor progress and make educational decisions if necessary. As noted in my
definition of test, an assessment may include a test, but also includes methods
such as observations, interviews, behavior monitoring, etc.
Measurement : beyond its general definition, refers to the
set of procedures and the principles for how to use the procedures in
educational tests and assessments. Some
of the basic principles of measurement in educational evaluations would be raw
scores, percentile ranks, derived scores, standard scores, etc.
Evaluation : Procedures used to determine whether
the subject (i.e. student) meets preset criteria, such as qualifying for
special education services. This uses assessment (remember that an assessment
may be a test) to make a determination of qualification in accordance with a
predetermined criteria.
