CTB - Clerical Test Battery Visual Speed and Accuracy Questions and Answers

Question 1

You are checking a shipping manifest by comparing the 'Original' list to the 'Copied' list. Which line item in the 'Copied' list contains an error?

Original List:
1. AX-4821-B, 105
2. CZ-9903-T, 50
3. FG-1745-K, 210
4. LP-6008-W, 75

Copied List:
1. AX-4821-B, 105
2. CZ-9903-T, 50
3. FG-1754-K, 210
4. LP-6008-W, 75

Accepted Answer

Line 3

Answer

The error is in Line 3. The original part number is 'FG-1745-K', but it was copied as 'FG-1754-K'. The digits '4' and '5' were transposed, which is a common type of clerical error.

Question 2

While verifying a list of serial numbers, a clerk notices that the original entry '89GHT561' was transcribed as '89GHT651'. Which type of clerical error does this represent?

Accepted Answer

Transposition

Answer

This is a transposition error, which occurs when two adjacent characters are swapped or interchanged. In this case, the '6' and '5' were switched. Substitution would be replacing a character with a different one (e.g., '5' with '8'), omission would be leaving a character out, and insertion would be adding an extra character.

Question 3

A clerk needs to verify that a mailing list of 500 addresses has been transcribed correctly into a new system. To ensure the highest accuracy while maintaining reasonable speed, which of the following is the most effective technique?

Accepted Answer

Use a ruler or piece of paper to isolate and compare each line, one item at a time.

Answer

Using a physical guide like a ruler or paper to isolate each line is the most effective solo technique. It prevents the eyes from skipping lines and makes direct, focused comparison easier, which reduces cognitive load and improves both speed and accuracy. While having a colleague read aloud can work, it introduces another potential source of error and is not always practical.

Question 4

When performing a visual accuracy check under a severe time constraint, what principle should guide a clerk's work?

Accepted Answer

Accuracy must be maintained, as unchecked data is better than incorrectly verified data.

Answer

The fundamental purpose of a verification or checking task is to ensure accuracy. Submitting work that has been partially checked but is 100% accurate is more valuable and professional than submitting a completed list that contains unverified errors. An incorrect 'verified' entry is worse than an entry that is simply left unchecked.

Question 5

A clerk is verifying a series of purchase orders. Which of the following transcription errors would likely have the most significant financial consequence for the company?

Accepted Answer

'Quantity: 100' transcribed as 'Quantity: 1000'

Answer

An error in quantity, especially one that multiplies the order by ten, has the most direct and significant financial impact. This would lead to a massive over-ordering of product, resulting in incorrect billing and inventory. The other errors are serious but are less likely to have such a large and immediate financial consequence.
