Module:	Types and criteria of language knowledge assessment
Topic:	Validity of the testing: Validity, reliability, practicality
Time:	80 minutes
Aim: Materials: Aids:	To let students analyse the validity, reliability, practicality of testing 1. Hughes, A. (2003) Testing for Language Teaching. Cambridge: Cambridge University Press.

Handout 1. Practicality, Reliability, Validity, Authenticity, and Washback
A. Practicality
An effective test is practical. This means that it

• 
  Is not excessively expensive,
  
• 
  Stays within appropriate time constraints,
  
• 
  Is relatively easy to administer, and
  
• 
  Has a scoring/evaluation procedure that is specific and time-efficient.
  

A test that is prohibitively expensive is impractical. A test of language proficiency that takes a student five hours to complete is impractical-it consumes more time (and money) than necessary to accomplish its objective. A test that requires individual one-on-one proctoring is impractical for a group of several hundred test-takers and only a handful of examiners. A test that takes a few minutes for a student to take and several hours for an examiner too evaluate is impractical for most classroom situations.
