STUDENTS-RELATED ISSUES
"Bad day"
Fatigue
Temporary Illness
If results have a huge difference ,there is not realibility
If students got "10" in the fist test, but they got a "5" in the another test ,probably they were cheating
If the teacher takes an exam one day and students got "10" ,the next time they should have the same results
It should be consistent and dependable
PRACTICALITY
To testing is necessary not to have a lot students , because teacher can't control is a student is cheating or not.
The time of the test should be balance ,if the teacher took 10 minutes creating the test , students need to take the similar time
A test should not be difficult to score
A test is practical when it is not to long for students or teachers
Test doen't need to be expensive
To create and effective test we need to be practical
