Castleport Test Prep

The ASWB Clinical Exam System

A complete LCSW study system: a clinical study guide, original vignette questions with full rationales, and version-aware coverage of both the current exam and the August 2026 update.

What the system includes

  • Clinical content-area study guide in ASWB's reasoning style
  • Original vignette questions with full rationales
  • Version-aware: aligned to your test date before or after August 3, 2026
  • Diagnosis refreshers and clinical ethics decision frameworks

Built the Castleport way

Every fact in the system maps to an official source and carries a verification status. Every question is original — written for this system, never scraped or recycled — with a full rationale explaining why the right answer is right and each distractor is wrong. When Association of Social Work Boards (ASWB) changes the exam, the system is versioned and updated, and the change is logged. Read our methodology and editorial standards.
