Distinction between Assessment Evaluation, Measurement and Test.Concept of Classroom assessment.

The definitions for each
are:

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.

Evaluation: Procedures used to determine whether the
subject (i.e. student) meets a 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.

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.
