Wjec Criminology Unit 3 AC1.2 Assess the usefulness of investigative techniques
This comprehensive resource pack is specifically designed for the WJEC Level 3 Applied Diploma in Criminology, covering the high-value Unit 3: AC1.2 (Assess the usefulness of investigative techniques in criminal investigations).
Since AC1.2 is a 20-mark task—the largest in the Controlled Assessment—this bundle focuses on moving students beyond simple description and into the Band 4 (16-20 marks) criteria of “clear and detailed assessment.”
What’s Included?
6 Interactive PowerPoints: Redesigned for active learning, including “Thinking Hard” challenges and digital research tasks.
Structured Student Workbook (Task 2): A complete digital and printable booklet that acts as the student’s primary research log and “cheat sheet” for their Controlled Assessment.
Specialist Lessons for 5 Key Techniques:
Surveillance: CCTV, Covert/Intrusive surveillance, and RIPA.
Forensics: DNA profiling, Fingerprints, and Blood Spatter analysis.
Profiling: Geographical (Canter’s Circle Theory) and Typological (FBI Top-Down).
Intelligence Databases: PNC, PND, and the National DNA Database.
Interviewing & Observation: The P.E.A.C.E model and Cognitive Interview techniques.
Assessment Mastery Session: A dedicated lesson for a 50-minute timed practice, including peer-marking grids and grade-band descriptors.
Key Features for Success:
“Usefulness” Mapping: Unlike AC1.1, these lessons train students to assess techniques based on Situations and Types of Crime (Violent, Property, Cyber).
Embedded Case Study Bank: Every lesson includes specific cases required for top marks, such as Operation Venetic (EncroChat), Sally-Ann Bowman, Colin Pitchfork, Adam Scott, Ronald Cotton, and the Colin Stagg/Rachel Nickell failure.
Ethical & Legal Integration: Covers the impact of the Bichard Inquiry (Soham Murders) and the S and Marper v UK ruling on human rights and privacy.
Exam Technique: Explicitly teaches students how to structure a 20-mark response that balances strengths against limitations using “evaluative connectors.”
Pedagogy:
The pack uses a retrieval-heavy approach to ensure students retain technical terminology (like Context Reinstatement or Familial DNA). Each lesson includes an “Hours worth of Homework” designed to push higher-ability students into independent research on cold cases and modern breakthroughs.
Perfect for: Delivering the most challenging part of Unit 3 with a clear, scaffolded path to Distinction-level grades.
