TEST CHECKS AND TECHNIQUES OF TEST CHECKING :
Carrying out detailed check of each and every transaction of a large business shall be time consuming for the auditor. In auditing the accounts of a business, every single copy is not usually checked by the auditor; what is usually done in practice is that a representative number of entries of each class are selected and checked and if they are found correct, the remaining entries are taken to be correct. This is known as Test Checking. In those organizations, where satisfactory internal check system is in existence, the auditor need not carry out detailed checking. He may adopt Test checking. It is a system of sampling employed by the auditor for the purpose of reducing the volume of detail checking involved in the audit. If, in Test Checking, he finds that the records checked by him are correct then no further detail checking need be carried out.
