Reliability. The right assessment tool produces the same results over time. So 
there's a consistency, or accuracy in these results. Here, you should consider whether 
the test can replicate results whenever it is used.
For example, if the students perform the same tasks simultaneously, then such 
assessment passes as reliable. 
Transparency means we have to make sure that our students know how 
assessment works. They need to know what we're looking for in an excellent answer 
or piece of work. They need to know what they must do to reach a pass mark. They 
need to know what would not get them a pass. In other words, we need to help our 
students to see that what is being assessed is their evidence of achievement of the 
intended learning outcomes, and that these outcomes are useful to them as goalposts 
for their studying. 
A good assessment tool is equitable, which means it doesn't favor or disfavor 
any participant. Fair assessments imply that students are tested using methods and 
procedures most appropriate to them. Every participant must be familiar with the 
test context so they can put up an acceptable performance. 
An educational assessment tool is used for evaluating students’ performance 
and their level of knowledge in a particular subject. Educational assessment tools 
can be used during the learning process or on an ongoing basis.
For example, in formative assessment, the teacher deploys different methods to 
track a student’s performance as learning progresses. This allows the instructor to 
identify and fix knowledge gaps as they move from one learning phase to another. 
But in summative assessment, the teacher waits till the end to measure the student’s 
performance using a rubric of expected learning outcomes.

In conclusion we can note that different assessment tools work for different 
types of educational assessment. So, while quizzes and surveys are suitable for 
formative assessment; end-of-term examinations with close-ended questions are 
better-suited for summative assessments.
