Internal Control Risk Assessment Scorer
Evaluates the strength of an organization's internal control framework using the five COSO components. Each component is rated 1–5 (1 = Very Weak, 5 = Very Strong). The weighted composite score determines the overall risk level.
Tone at the top, integrity, ethical values, governance structure.
Identification and analysis of relevant risks to achieving objectives.
Policies and procedures that help ensure management directives are carried out.
Quality and timeliness of information systems and communication channels.
Ongoing evaluations and separate evaluations to ascertain control effectiveness.

Formula
Weighted Composite Score (1–5 scale):
Composite = (CE × 0.25) + (RA × 0.20) + (CA × 0.25) + (IC × 0.15) + (MON × 0.15)
Normalized Score (0–100 scale):
Score100 = ((Composite − 1) / 4) × 100
Risk Classification:
- 80–100: Low Risk
- 60–79: Moderate-Low Risk
- 40–59: Moderate Risk
- 20–39: High Risk
- 0–19: Critical Risk
Where: CE = Control Environment, RA = Risk Assessment, CA = Control Activities, IC = Information & Communication, MON = Monitoring Activities. Each rated 1 (Very Weak) to 5 (Very Strong).
Assumptions & References
- Based on the COSO Internal Control – Integrated Framework (2013), the globally accepted standard for internal control design and evaluation.
- Component weights reflect relative importance: Control Environment and Control Activities are weighted highest (25% each) as foundational elements; Information & Communication and Monitoring are supporting components (15% each).
- Ratings are subjective assessments by auditors, management, or control owners using a 1–5 Likert scale derived from control testing, walkthroughs, and documentation reviews.
- A score of 1 represents Very Weak (pervasive deficiencies); 5 represents Very Strong (fully effective, well-documented controls).
- This tool provides a relative risk indicator. It does not replace a full audit or replace professional judgment under PCAOB AS 2201, SOX Section 404, or equivalent standards.
