Week 2

Trace the feedwater path from storage through treatment, deaeration, pumping, and boiler entry.
Classify common water-treatment methods by purpose, including softening, demineralization, oxygen scavenging, and chemical control.
Interpret key water-test parameters such as pH, conductivity, hardness, alkalinity, and dissolved oxygen.
Diagnose carryover, scale, corrosion, and foaming from sample operating data.
Complete 20 practice questions on feedwater systems and water treatment with at least 80% accuracy.

Identify the function and failure symptoms of safety valves, feedwater regulators, economizers, air preheaters, and sootblowers.
Sequence pre-start checks for major boiler auxiliaries and fittings.
Map required fittings and accessories to their operating and safety purposes.
Explain how auxiliary failure affects combustion, draft, feedwater, and steam output.
Complete 20 practice questions on auxiliaries, fittings, and accessories with at least 80% accuracy.

A labeled boiler auxiliary flow sketch with at least 12 components and a 20-question quiz score of 80% or higher.

Week 4

Write a step-by-step startup checklist covering pre-start inspection, warm-up, and pressure rise.
Describe normal-operation monitoring actions for water level, pressure, temperature, combustion, and draft.
Sequence a controlled shutdown, including load reduction, fuel cut-off, and cooldown.
Apply emergency actions for low water, high pressure, flame failure, and tube leak scenarios.
Perform a timed dry-run walkthrough of startup and shutdown using the checklist.

A timed dry-run walkthrough scored against a 20-point rubric with at least 90% completion.

Week 5

Classify boiler types by construction, firing method, pressure range, and tube arrangement.
Relate boiler design features to water circulation, heat transfer, and operational limits.
Interpret control loops for feedwater, fuel, air, and steam pressure.
Explain interlocks, flame safeguards, and automatic-operation modes during normal and abnormal conditions.
Complete 25 mixed practice questions on boiler design and controls with at least 80% accuracy.

A boiler-type comparison matrix covering at least 8 designs plus a 25-question quiz score of 80% or higher.

Week 6

Build an inspection and testing schedule covering daily, periodic, and annual checks.
Describe hydrostatic testing, non-destructive testing, and safety-valve testing procedures.
Identify code and regulatory requirements for boiler operation, records, and operator responsibilities.
Practice emergency response actions for fire, explosion risk, low water, and overpressure.
Complete 25 mixed practice questions on maintenance, inspection, testing, safety, and codes with at least 80% accuracy.

An inspection and testing checklist plus an emergency-action flowchart, with a 25-question quiz score of 80% or higher.

Week 7

Rework every missed item from weeks 1 through 6 and record the corrected concept.
Complete 60 mixed questions weighted toward combustion, fuels, draft, feedwater, and water treatment.
Recalculate excess air, stack-loss indicators, water-test interpretations, and treatment adjustments.
Simulate troubleshooting for poor combustion, high dissolved oxygen, scale, and carryover.
Explain at least 20 corrected concepts aloud without notes.

An error log with 20 corrected concepts and a 60-question mixed score of 85% or higher.

Week 8

Complete a full-length timed mock exam covering all eight domains.
Review every mock-exam miss and classify it by domain and cause.
Re-test weak areas from maintenance, inspection, testing, safety, and regulations.
Build a final one-page formula, procedure, and code-concept reference sheet.
Score at least 85% on a second timed 40-question remediation set.

A full-length mock exam score report, a remediation log, and a second 40-question set scored at 85% or higher.

Week 2: Score at least 80% on both the combustion/draft quiz and the feedwater/water-treatment quiz, and submit both summary deliverables.

Week 4: Complete the startup/shutdown dry-run walkthrough at 90% or higher on the rubric and score at least 80% on the auxiliaries quiz.

Week 6: Score at least 80% on the design/controls quiz and the maintenance/safety quiz, and submit both associated checklists.

Week 8: Complete the full-length timed mock exam and a 40-question remediation set with the remediation score at 85% or higher.
