Hello,

Let me clearify the meaning of the statement.

An aptitutde test is a test which is taken to understand or assess what a candidate is able to do or to predict about a persons knowledge in a specific field or area.

To assess this knowledge aptitude tests include various DATs which means Different Aptitude Tests to assess the knowlege of the person in various fields like verbal reasoning, numerical ability, abstract Reasoning, clerical speed and accuracy, mechanical reasoning, space relations, spelling and language usage.

A celerical aptitude test specifically assesses proficiency at tasks related to clerical or administrative work, helping testees to determine which candidates have the skill level necessary for the job.Hence clerical speed is the speed of how fast a test taker can solve such questions.

Accuracy tests are tests which measure how many correct answers you give and how fast you give the correct answers compared to other competitors.

These two tests are very important and are known as pre employment tests.

Hope this helps.
