Routine Checking and Test Checking — how this chapter is examined
Routine Checking and Test Checking is Unit 4, Part B (Preliminaries of Auditing) of the WBCHSE
Commercial Law and Preliminaries of Auditing (CLPA) syllabus, worth 6 of the 40 marks in the
Semester III (Class XII) paper. Semester III is a 100% Multiple Choice Question (MCQ) paper
— every mark in the real WBCHSE examination for this unit is earned through 1-mark MCQs.
How this chapter is organised
The MCQs in this chapter (grouped under "Multiple Choice Questions") are the content that
mirrors your real Semester III paper for this unit exactly. In addition, this chapter includes
a small set of Case Problem questions — realistic fact-pattern scenarios applying the
difference between routine checking and test checking. These Case Problems are supplementary practice, not part of the 6-mark MCQ paper — the real exam for this unit will not ask you to
write a case analysis. They exist here because applying the distinction to a real audit
scenario is the best way to genuinely understand WHEN each technique is appropriate.
This chapter is best understood as the natural next step after Class XI's Internal Control
System chapter and Class XI Ch8's Internal Audit coverage: once an auditor has evaluated a
business's internal control and internal check systems, the auditor must decide HOW to actually
carry out the verification work itself — checking every single transaction (Routine Checking), or examining only a representative sample (Test Checking). This choice is one
of the most practically important decisions in planning any real audit, and it connects directly
to Class XII Ch3's coverage of Audit Planning and the Audit Programme.
WBCHSE's Commercial Law and Preliminaries of Auditing syllabus draws on the same auditing
principles of routine and sample-based verification that are also taught in CBSE/NCERT
Accountancy's coverage of internal checks on cash and bank transactions — a student who
understands why an auditor cannot check every single entry in a large business will recognise
the same underlying logic (the cost-benefit trade-off of 100% verification) in any other board's
accountancy or auditing content.
