NCCER Module 22204: Scrapers Course Syllabus
Course Title: Scrapers Module ID: 22204-13 (Heavy Equipment Operations Level 2) Training Hours: 17.5 Hours (Classroom and Hands-On) Edition Reference: NCCER Heavy Equipment Operations, Fourth Edition or later Prerequisites: Completion of NCCER Heavy Equipment Operations Level 1 (including core safety and basic operations modules) or equivalent experience. Trainees should have basic knowledge of heavy equipment safety, identification, and soils/grades.
Course Description
This module provides comprehensive training on scrapers used in earthmoving and site preparation. It covers the various types of scrapers, associated safety practices, operator responsibilities, inspection and maintenance procedures, and fundamental operating techniques including startup, shutdown, loading, hauling, and spreading material.
The training emphasizes safe, efficient operation in compliance with OSHA guidelines and manufacturer recommendations. Upon completion, trainees will be prepared for NCCER certification assessments, including written exams and performance verifications.
Examples of common scraper types in construction: single-engine wheeled, twin-engine, and elevating scrapers.
Learning Objectives
Upon successful completion of this module, trainees will be able to:
- Identify and describe the major types of scrapers and their applications in site work.
- Recognize and explain key components, instruments, and controls of scrapers.
- Apply safety guidelines and hazard recognition specific to scraper operations.
- Perform pre-start inspections, basic preventive maintenance, and lubrication tasks.
- Demonstrate proper startup, shutdown, and safe operating procedures.
- Execute basic scraper operations, including cutting, loading (e.g., push-loaded, self-loaded, straddle loading), hauling, dumping, and spreading material.
Course Outline

Instructional Methods
- Classroom lectures and discussions
- Multimedia presentations (videos of operations)
- Hands-on practice (simulator or live equipment under supervision)
- Group activities and case studies on safety incidents
Assessment Methods
- Written module examination (multiple-choice, covering theory and safety)
- Performance profile tasks (e.g., complete pre-start inspection, demonstrate safe loading/hauling cycle)
- NCCER Performance Verification available for credentialing
Passing Criteria: 70% or higher on written exam; satisfactory completion of performance tasks.
Required Materials
