International Sailing License (SLC) Self-Assessment

A self-assessment to prepare for practical, in-person, on-the-water assessments with a NauticEd Assessor/Instructor to become licensed to charter boats worldwide.

What is the SLC Self-Assessment?

The SLC Self-Assessment is a tool to “self-assess” and prepare for your practical, on-the-water, skills that are required to charter a sailboat worldwide with the International Sailing License and Credentials (SLC) license. While the self-assessment is intended to be sent to your Assessor/Instructor, you’re welcome to use it personally.

How is the SLC Self-Assessment Used?

Since the Self-Assessment is used to prepare for an in-person and on-the-water assessment by a qualified Assessor/Instructor, it is NOT SCORED. Instead, you (and the instructor if you send it) will receive an emailed list of (a) areas in which you need help, (b) areas wherein you may be a bit rusty, and (c) all the glorious skills that you have mastered.

Your Assessor/Instructor then can discuss the results with you in detail. For example, perhaps you need more practice to “shake off the rust” (if you haven’t sailed in a while), or for some items you may want a refresher or additional training.

Why is the SLC Self-Assessment Important?

The SLC in-person, on-the-water, assessment with an Assessor/Instructor is PASS/FAIL. The assessor does not pass or fail based on opinion; rather, they evaluate whether your demonstrated skills meet national and international benchmarks.

Simply, it behooves you to self-assess so that you can fully prepare for the actual assessment. And even if you’re just “monkeying around” with this form, it’ll give you an excellent sense of your strengths and weaknesses when it comes to chartering a boat internationally.

Important Assessment Points to Keep in Mind:

  • The SLC is not a casual certification—it is an international sailing license that requires verified competence.
  • The assessor’s job is not only to evaluate you, but also to help identify any critical weaknesses that may put you, your crew, or your vessel at risk.
  • Attempting to “rush” the assessment by overstating your abilities may result in not passing and the need for additional assessment and training sessions.
  • It is completely acceptable and encouraged to indicate areas where you need a refresher or further instruction. Doing so shows maturity, responsibility, and dedication to becoming a competent skipper.
  • Should your session include more training time, you will leave a more confident and capable boater—and ultimately safer and more qualified for bareboat charter operations.

SLC Self-Assessment Instructions

1. Complete the Self-Assessment below.

2. Each question has 3 answers. Very simple:
– “I’m Good to Go“: you feel confident and competent with this skill.
– “I’m a Little Rusty“: you are familiar with the skill, but are likely out of practice (i.e., haven’t done it in a while) and are not fully confident in performing the skill in an on-water assessment.
– “I Need Help“: you’re not really confident or practiced in this skill and likely need help with it.

3. When complete, add any additional comments and email info – including the assessor/instructor info (optional) – for a summary.

*Note: we’re not collecting your email address for marketing, signing you up for anything, or any of that bait-n-switch nonsense. This is strictly a self-assessment, and results go only to those who you assign at the end.

Give Yourself an Honest Assessment

Being honest with your self-assessment before working with a boating assessor or instructor is crucial for your growth and safety. It helps the instructor tailor the training to your actual needs, reinforce weak areas, and build real competence. Overestimating your abilities can slow your progress, create risky situations, or result in a failed license assessment—while honesty sets you up for a more efficient, personalized learning experience. And remember, an on-water SLC License Assessement is pass/fail!
