How to Read an ASE Damage Estimate Like a Pro (B6 Prep)

Estimating Is the Skill That Pays Bills

In a collision shop, the estimator decides whether the shop makes money on a job or loses money. They decide whether a customer's vehicle gets repaired correctly or gets a Band-Aid fix that fails later. They're the bridge between insurance adjusters, repair techs, and customers.

The ASE B6 Damage Analysis & Estimating test is built to certify that an estimator actually understands what they're doing — beyond just clicking line items in CCC ONE or Mitchell Estimating.

Let me walk you through how to read a damage estimate the way the B6 test wants you to think.

The B6 Test Structure

65 scored questions, 90 minutes. Categories:

• Vehicle Construction and Parts Identification (~10 questions)
• Estimating Procedures (~15 questions)
• Computer-Assisted Estimating (~8 questions)
• Damage Analysis and Assessment (~14 questions)
• Customer Relations and Sales Skills (~5 questions)
• Calculations (~6 questions)
• Vehicle Safety Inspection (~7 questions)

Estimating procedures + damage analysis = 29 questions = 45% of the test. That's your prime study target.

The Three Most Important Estimating Terms

R&R vs. R&I

You will see this distinction tested repeatedly. Memorize it cold.

• R&R = Remove and Replace — The part comes off the vehicle and a NEW part goes on. You're removing damaged, installing replacement.
• R&I = Remove and Install — The same part comes off and goes back on. You're removing it to gain access to repair other damage, then reinstalling the same part.

A door is R&I if you take it off to repair the underlying quarter panel, then reinstall the same door. The door is R&R if you're replacing the door itself.

Estimates often have line items for both R&R and R&I in the same job. Reading them wrong means you scope the job wrong, the parts order is wrong, and the labor calc is wrong.

Repair Time vs. Refinish Time

Estimating software gives you:

• Repair time — Labor to fix the dent, replace the panel, etc.
• Refinish time — Labor to paint the panel after repair
• Two-stage refinish allowance — Extra time for basecoat/clearcoat applications
• Color blend allowance — Extra time when blending into adjacent panels

The B6 test asks specifically about adding these correctly. A common trap: forgetting to add the two-stage refinish allowance when the vehicle uses a basecoat/clearcoat system (which is almost every modern vehicle).

OEM vs. Aftermarket vs. LKQ Parts

• OEM — Original Equipment Manufacturer. Branded factory parts. Most expensive.
• Aftermarket — Made by non-OEM manufacturers to OEM specs. Often CAPA-certified for quality.
• LKQ — Like Kind & Quality. Used or salvage parts.

Insurance estimates may require certain part types per the customer's policy. The B6 will give you scenarios: "The insurance policy specifies LKQ parts. What is the next step?" Answer involves communicating with the customer about quality differences and getting their authorization.

How a Pro Reads an Estimate Top-to-Bottom

When the B6 shows you a sample estimate (or describes one in a scenario), here's the order of reading:

1. Vehicle Identification

• Year, make, model, trim, VIN
• Mileage (affects parts decisions and total loss thresholds)
• Pre-existing damage notation

If anything's missing or inconsistent (VIN doesn't match body type), the estimate is suspect.

2. Damage Map / Damage Photos Section

Modern estimates have photos with annotations:

• Direct damage (the impact area)
• Secondary damage (transferred from primary impact)
• Pre-existing damage (PEA — pre-existing accident)

The B6 expects you to recognize:

• Front impact → check radiator support, frame rails, suspension geometry
• Side impact → check rocker, B-pillar, opposite door for unibody twist
• Rear impact → check trunk floor, rear rails, fuel tank/system

Secondary damage is the most common missed item. A front impact strong enough to deform the radiator support almost certainly affected the upper tie bar and possibly the strut towers. If those aren't on the estimate, the estimate is incomplete.

3. Line Items

Each line item should have:

• Part name
• OEM/Aftermarket/LKQ designation
• Part number
• Quantity
• List price
• Labor operation (R&R, R&I, repair, refinish)
• Labor hours

Common errors to spot:

• Missing fasteners and clips. Many panels require new fasteners/clips that aren't in the standard labor allowance.
• Missing one-time-use parts. Headlight bolts, certain bumper retainers, airbag-related fasteners are often one-time-use per OEM. Reusing them is wrong.
• Missing R&I operations. To get to a damaged radiator, you have to R&I the fan, the grille, possibly the bumper. If those aren't on the estimate, the labor allowance won't cover the actual work.

4. Sublet / Outside Operations

Items sent to outside specialists:

• Wheel alignment
• ADAS calibration (radar, camera, lidar) — increasingly common, often $300-$800
• Glass replacement (if specialty)
• Frame straightening (if shop lacks equipment)
• Pre-scan / post-scan (most insurers now require both)

The B6 specifically tests ADAS pre/post scan procedures. Most modern vehicles require a scan before repair and a scan after to verify all modules are functioning and re-calibrate as needed.

5. Calculations Section

At the bottom:

• Parts total
• Labor total (often split by body labor, refinish labor, mechanical labor — each may have a different shop rate)
• Sublet total
• Sales tax (varies by state, often applied to parts and sublet but not labor)
• Total estimated cost
• Customer's deductible
• Insurance company's responsibility

The B6 has calculation questions where you'll be given line items and asked to compute the total. Practice these. Make sure you know:

• Labor hours × labor rate = labor cost
• Refinish hours × refinish rate (often different from body labor rate)
• Tax applied only to specified line items

Damage Analysis Beyond the Software

The B6 doesn't just test estimating software entry — it tests damage analysis judgment.

Pre-Scan and Post-Scan

• Pre-scan: Performed before repair work. Identifies all stored DTCs (Diagnostic Trouble Codes), tells you what modules were affected by the collision, and creates documentation.
• Post-scan: Performed after repair. Verifies no remaining DTCs, confirms all systems functional, and creates closing documentation.

Most modern insurance contracts require both. The B6 will ask scenarios about when each is performed and what they're used for.

Hidden Damage Recognition

Common hidden damage patterns:

• Suspension geometry shifts — Front impacts often bend lower control arms or knuckles, even when the visible damage is "just bumper and grille."
• Frame rail kinks — Compressed rails after front impact, identified by measurement systems
• HVAC condenser bends — Often missed; only show up as poor AC performance after repair
• Wiring harness damage — Pinches behind the bumper or under the radiator support

A complete estimate accounts for hidden damage allowance OR requires a supplement after teardown.

Total Loss Calculations

• Actual Cash Value (ACV) — What the vehicle was worth pre-loss
• Repair Cost Threshold — Typically 70-80% of ACV depending on state and insurance
• If estimated repair cost exceeds threshold, vehicle is declared total loss

The B6 will give you scenarios: "Vehicle ACV is $12,000. Repair estimate is $9,500. What is the recommendation?" If state threshold is 70%, that's $8,400 — repair exceeds threshold, recommend total loss.

Customer Relations: Don't Skip This Section

5 questions on customer relations seems small, but it's easy points:

• Disclosure of part types — Customers must be told if aftermarket or LKQ parts are being used
• Authorization requirements — Supplements require customer authorization before work proceeds
• Repair timeline communication — Customers should be given a realistic timeline, including parts wait times and sublet operation scheduling
• Vehicle safety inspection results — Customer must be informed if any safety-related items (brakes, tires, steering) were found beyond the collision damage

The B6 wants you to recognize that a damage estimate isn't just a number — it's a communication tool between shop, insurer, and customer.

How to Study for B6

1. Get familiar with at least one estimating software — CCC ONE, Mitchell, or Audatex. Most shops use one of these. Even if you're new, request shadowing time with the shop estimator.
2. Practice calculations. Labor + refinish + tax problems. Drill them.
3. Study common damage patterns by impact direction. Front, side, rear, rollover. Each has expected primary + secondary damage.
4. Memorize R&R vs R&I distinction. This is the most-tested concept on B6.
5. Take a full B6 practice simulation under timed conditions. Get used to scanning long estimate scenarios quickly.

The Mindset That Passes B6

Reading an estimate as a pro means asking "what's NOT on this estimate that should be?" — not just verifying the line items that ARE on it.

That's what the B6 grades. Develop the habit of reading skeptically: every estimate is incomplete until proven otherwise.

Pass the B6 and you'll be a better estimator at work, too. That's the real win.
