What you’ll learn

  1. Screening system and listsExplain screening roles, sanctions programs, and the restrictions behind list entries.Screening combines lists, program rules, and decision rights—not a yes-or-no name match.
  2. Data, transactions, and holdsUse identifiers, transaction triggers, ownership checks, holds, and execution controls. Identify tests and metrics that reveal screening weaknesses.Better data, event screening, and documented holds connect alerts to operational decisions. Periodic testing checks whether updates, triggers, review, release, and records still work.

Questions this course answers

What is a sanctions-screening alert?

An alert signals a possible connection; a reviewer must compare identifiers, rules, and transaction facts.

Why must a reviewer identify the sanctions program behind a list entry?

The applicable program determines what conduct or property is restricted and which jurisdictional rules matter.

Put a potential sanctions match into a sensible review order.

The organization first contains the unresolved alert, compares identifiers, interprets the applicable rule, and records the decision.

Why can onboarding screening be insufficient?

Transaction events and relationship changes can create new facts that require screening or escalation.

What does effective testing examine?

Testing checks the complete control path from current data and event triggers through decision, release, and evidence.
