Internal Control Questionnaire (ICQ) and Internal Control Evaluation (ICE) : The internal control questionnaires show the area where weakness occur or likely to occur. They do not give any idea of the importance of those weaknesses. The Internal Control Evaluation brings to light importance of those weakness disclosed by ICQ. Main points of distinctions are:
(i) ICQ incorporates a large number of detailed questions but does not attempt to distinguish their relation in materiality. ICE isolates the main control objectives within the area of review.
(ii) Weaknesses are highlighted by answer “Yes” on ICE compared with „No‟ on ICQ.
(iii) Answer „no‟ in ICQ indicates a weakness real or potential, but its significance is not revealed. Whereas ICE requires audit personnel to state whether, an apparent weakness may prove to be material in relation to the accounts as a whole.
