Does Cisco Publish a CCIE Collaboration Pass Rate?
If you searched for "CCIE Collaboration pass rate 2026" hoping for a clean percentage, here's the honest answer: Cisco does not publish official pass/fail statistics for the 350-801 CLCOR exam or for the CCIE Collaboration v3.1 practical exam. Any specific number you find circulating on forums or third-party blogs is an estimate, an anecdote, or a fabrication - not a figure that comes from Cisco Systems, Inc. itself.
That absence of a public number is itself useful data. It means the smartest way to evaluate your chances isn't to chase a mythical percentage - it's to understand the actual mechanics of the certification path: exam structure, blueprint weighting, retake policy, and time constraints. Those are documented facts, and they tell you far more about your realistic odds than a rumored pass rate ever could.
This article walks through what Cisco does confirm, so you can build an accurate risk picture instead of anchoring to numbers nobody can verify. For a broader look at exam difficulty itself, see How Hard Is the CCIE Collaboration Exam? Complete Difficulty Guide 2026.
Why "Pass Rate" Means Two Different Things Here
Before you can even talk meaningfully about pass rate, you need to separate the two exams that sit behind the CCIE Collaboration credential. Confusing them is one of the most common mistakes candidates make when researching this cert.
350-801 CLCOR v2.0 - The Qualifying Core
Implementing and Operating Cisco Collaboration Core Technologies is a 120-minute, English-language, proctored exam delivered at a Pearson VUE test center or via OnVUE online proctoring. The fee is USD 400 before applicable tax. Passing it earns Cisco Certified Specialist - Collaboration Core, and it satisfies the core requirement for both CCNP Collaboration and CCIE Collaboration. There are no formal prerequisites.
- Six qualifying-core domains - not the CCIE lab blueprint
- Pass/fail delivered as a computer-scored result at the test center
- Blueprint version CLCOR v2.0, copyright 2025
CCIE Collaboration v3.1 Practical Exam - The Lab
Passing CLCOR alone does not award CCIE. The practical exam is a separate, in-person, 8-hour lab priced at USD 1,600. Combined first-attempt base fees for core plus lab total USD 2,000, excluding tax, training, and travel - and excluding any retake fees if either attempt fails.
- Must be completed within 3 years of passing the CLCOR core
- Full-day, hands-on format very different from the multiple-choice core exam
- Certification, once earned, is valid for 3 years before recertification is due
Because these are two structurally different exams - one a timed knowledge test, the other a full-day practical assessment - any single "pass rate" figure that lumps them together is misleading by design.

How Domain Weighting Shapes Your Odds
Since Cisco doesn't publish a pass rate, the most reliable proxy for difficulty is the CLCOR blueprint itself - specifically, which domains carry the most weight. Two domains alone account for more than half the exam:
| Domain | Weight | Why It Matters for Your Result |
|---|---|---|
| On-Premises Call Control | 30% | Largest single domain; weak call-control fundamentals sink your overall score fastest |
| Cloud and Hybrid Services | 25% | Second-largest; increasingly central as deployments shift hybrid |
| Infrastructure and Design | 15% | Foundational architecture knowledge, tested throughout other domains too |
| Protocols and Endpoints | 10% | Smaller weight but appears in mixed-topic questions |
| Voice Gateways and Session Border Controllers | 10% | Narrower scope, but easy to under-prepare |
| Media and QoS | 10% | Often the domain candidates skip studying - a mistake |
Because On-Premises Call Control and Cloud and Hybrid Services together make up 55% of the blueprint, a candidate who is strong across every other area but weak in these two is statistically the most likely to fail the core exam. This is the single most actionable "data point" available to you in the absence of a published pass rate - allocate study time in proportion to blueprint weight, not personal interest. For a domain-by-domain breakdown of exactly what each area tests, see CCIE Collaboration Exam Domains 2026: Complete Guide to All 6 Content Areas.
Key Takeaway
Spend disproportionate study time on On-Premises Call Control and Cloud and Hybrid Services - together they're 55% of the CLCOR score, and weakness there is the most likely single cause of a failed attempt.
Retake Mechanics: The Real Numbers Behind Failure
If there's one set of hard numbers that functions as a real "pass rate proxy," it's Cisco's own retake policy. These waiting periods exist precisely because failure is a documented, planned-for outcome of the process - not a fluke.
- CLCOR core retest wait: 5 calendar days, counted from the day after a failed attempt
- CCIE Collaboration lab retest wait: 30 calendar days, counted from the day after a failed attempt
- Time limit to complete CCIE requirements: 3 years from the date you pass CLCOR
- Confidentiality: Personal notes are prohibited during the exam, and Cisco's exam confidentiality agreement applies to both the core and the lab
A 30-day mandatory wait after a failed lab attempt is a meaningful signal: Cisco builds its scheduling policy around the expectation that lab failures happen and require substantial preparation time before a retry is even permitted. Combined with the USD 1,600 lab fee applying again on each attempt, this is the real financial and time cost of an unsuccessful attempt - figures far more concrete than any rumored percentage. For a fuller accounting of what a failed attempt costs across scheduling, fees, and lost time, see CCIE Collaboration Pass Rate 2026: What the Data Shows and the passing-score mechanics in CCIE Collaboration Passing Score 2026: Exactly What You Need to Pass.
Who Actually Hires for This Credential
Pass rate speculation aside, the reason candidates pursue CCIE Collaboration is career impact, and that's driven by who values the credential in practice. Organizations running large-scale Cisco unified communications environments - call control platforms, session border controllers, voice gateways, and hybrid cloud collaboration deployments - look for this certification specifically because the CLCOR core and the CCIE lab both test hands-on operational competence with those exact technologies, not just conceptual knowledge.
Enterprises with heavy on-premises call control footprints (the largest blueprint domain at 30%) and organizations mid-migration toward cloud and hybrid collaboration architectures (25% of the blueprint) are the most natural employers for this skill set, since those two areas map directly onto the systems they operate day to day.

How to Improve Your Personal Pass Probability
Without an official baseline pass rate to compare against, your energy is better spent controlling the variables you actually influence: domain coverage, timing, and realistic practice under exam conditions.
On-Premises Call Control & Infrastructure and Design
- Build depth in the 30%-weighted domain first since it's the single largest scoring block
- Layer in Infrastructure and Design (15%) since it underpins call-control architecture questions
Cloud and Hybrid Services
- Dedicate focused time to the 25%-weighted domain - the second-highest scoring block
- Practice scenario-based questions that blend on-prem and cloud call flows
Remaining Domains & Timed Practice
- Cover Protocols and Endpoints, Voice Gateways and SBCs, and Media and QoS (each 10%)
- Run full 120-minute timed practice sessions to simulate CLCOR exam-day pacing
This weighting-driven sequence is the core logic behind a full study plan - for the complete first-attempt strategy including lab preparation, see CCIE Collaboration Study Guide 2026: How to Pass on Your First Attempt. Running realistic, timed practice questions against the actual CLCOR blueprint on our practice test platform is one of the most direct ways to expose weak domains before exam day rather than after a failed attempt starts a 5-day retest clock.
It's also worth remembering that recertification isn't a one-time event: CCIE certification is valid for 3 years, and maintaining it requires 120 CE credits through qualifying learning activities and/or passed certification exams. Passing the CLCOR core once is the entry point, not the finish line - plan your continuing education path early rather than scrambling near expiration.
Key Takeaway
Use practice exams that mirror the CLCOR blueprint weighting to find weak domains before test day - it's a more reliable predictor of your outcome than any unofficial pass-rate rumor.
Frequently Asked Questions
Cisco does not publish an official pass rate for the 350-801 CLCOR exam or the CCIE Collaboration v3.1 lab. Any specific percentage circulating online is unofficial and unverifiable.
Use the documented blueprint weighting instead. On-Premises Call Control (30%) and Cloud and Hybrid Services (25%) make up 55% of the CLCOR score, so mastery there is the strongest predictor of a passing result.
Five calendar days, counted from the day after your failed attempt, before you can schedule a retest.
Thirty calendar days, counted from the day after your failed attempt, before you can schedule the lab again.
No. Passing 350-801 CLCOR earns Cisco Certified Specialist - Collaboration Core and satisfies the core requirement for CCIE Collaboration, but you must also pass the separate 8-hour CCIE Collaboration v3.1 practical exam within 3 years of passing the core.
