Answers for every step of your journey.

Scientology Extension Courses provide a structured way to study the books and lectures of L. Ron Hubbard from home, wherever you are in the world.

Each course guides you through a specific book or lecture series through a sequence of lessons. You study the corresponding materials, answer questions about what you have studied and submit your lessons online.

Every submitted lesson is personally reviewed by a human Extension Course Supervisor, who provides individualized feedback and helps you progress through the course.

You are welcome to contact us and we can help you choose an appropriate starting point based on what interests you and which materials, if any, you have already studied.

If your goal is to follow the complete route systematically, we can also help you begin at the appropriate point and progress through the sequence from there.

You can also browse the available courses or use the Route Planner to explore the sequence at your own pace.

If Dianetics is what interests you, you can also review Dianetics: The Modern Science of Mental Health as a starting point.

Extension Courses are available to anyone who wants to study the materials of Dianetics and Scientology in a structured way.

You do not need to live near a Church of Scientology, and you do not need to live in Puerto Rico.

The program is specifically suited to students who want the benefits of supervised study while studying from home.

Yes.

Our Extension Courses are delivered online, so students can enroll and study from Puerto Rico or from elsewhere in the world.

Your location does not prevent you from completing lessons, receiving personalized supervision or communicating with your Course Supervisor.

Physical books, lecture materials and course packs can also be shipped internationally.

Absolutely.

If you are unsure where to begin, tell us what you have already studied and what you are most interested in learning.

We will be happy to help you choose an appropriate Extension Course and get started.

Yes.

Our Extension Courses allow you to study L. Ron Hubbard’s books and lectures from home while completing your course lessons through our online system.

There are no live classes that you have to attend at a particular time. You can study from wherever you are and communicate directly with your Course Supervisor as you progress.

Yes. One of the major purposes of the Extension Course program is to provide a structured route through the materials.

The Basics form the foundation, followed by the Congresses and then the Professional and Advanced Clinical Course lectures. As you continue through the route, each development builds upon those that came before it.

If your goal is to study L. Ron Hubbard’s works systematically rather than simply reading individual titles in isolation, the Extension Course route provides a way to progress through the materials in sequence.

The books and lectures span many years of research and development.

Studying them in sequence allows you to see how one discovery develops into the next and how later materials build upon earlier ones.

This becomes especially important with the Congresses and Advanced Clinical Course lectures, where developments, demonstrations, lectures and related writings are interconnected.

No.

There are no scheduled online classes that you have to attend at a particular hour.

You study according to your own schedule, work through your lessons and submit them for review through the online course system.

This makes Extension Courses particularly convenient for students in different countries and time zones.

Yes, we recommend it.

You can choose a schedule that works with your life, but making regular time for your Extension Course helps you maintain momentum and continue progressing through the materials.

We encourage students, whenever possible, to work through and submit at least one lesson each week for review.

The process is straightforward:

1. Choose the Extension Course you want to study.
2. Enroll online.
3. Obtain the corresponding L. Ron Hubbard book or lecture series if you do not already own it.
4. Study the material and work through each lesson in sequence.
5. Submit your lesson answers for review through the online course system.
6. Your human Course Supervisor personally reviews the lesson and provides individualized feedback.
7. Continue through the lessons until you complete the course.

You can also communicate directly with your Course Supervisor through the in-app messaging system whenever you have questions or need guidance.

You can study at a pace that fits your schedule.

There is no requirement to attend at a particular hour, but regular study is strongly encouraged.

Whenever possible, we recommend maintaining steady progress and submitting at least one lesson each week.

The length varies depending on the book or lecture series being studied.

Browse the course catalog to compare information such as the number of lessons and estimated study time, giving you an idea of each course’s scope before you enroll.

Each lesson guides you through important material in the corresponding book or lecture series and helps you identify and understand the key data, principles and concepts being studied.

But the purpose is not simply to memorize information or answer questions correctly. A major goal of Scientology study is to develop an understanding of the material that you can use and apply in your own life.

The lessons are therefore designed to help you think with the material, recognize how the principles relate to real situations and develop greater certainty in your ability to apply what you have learned.

Some questions ask you to explain concepts in your own words, while others may ask you to give examples, make observations, or draw, diagram or sketch something. This helps ensure that you are not simply reading through the material, but are gaining a practical and conceptual understanding of it.

As you progress through the course, each lesson builds upon what came before, helping you develop both a fuller understanding of the material and an increasing ability to put that knowledge into practice.

No. All Extension Course questions are essay questions.

Students answer in their own words based on the materials they are studying.

Some lessons also ask the student to draw, diagram or sketch something as part of the assignment.

Every lesson is personally reviewed by a human Extension Course Supervisor, and the student receives personalized feedback on each lesson submitted.

Students can also correspond directly with their Course Supervisor through the in-app messaging system. This gives them an opportunity to ask questions, request clarification or receive guidance on the course materials as they progress.

No.

Your Extension Course lessons are personally reviewed by a human Course Supervisor.

The Supervisor reads your submitted answers and provides feedback specifically related to your lesson.

The online system is used to deliver and submit the course, but the supervision itself is personal.

Every lesson is personally reviewed by a human Extension Course Supervisor.

Your Supervisor reviews your answers, provides personalized feedback and follows your progress throughout the course.

If something needs clarification or additional work, your Supervisor can communicate with you directly about it.

Yes.

You can correspond directly with a Course Supervisor through the in-app messaging system. Use it to ask questions about your course, or request assistance if you run into difficulty.

Your messages will be answered by a Course Supervisor, so even though you are studying remotely, you are not studying without supervision.

Yes.

Each Extension Course is studied alongside the corresponding L. Ron Hubbard book or lecture series.

The book or lectures contain the material you will be studying, while the Extension Course lessons guide you through that material.

The required book or lecture series is separate from the Extension Course enrollment unless the course listing specifically states otherwise.

If you already own the correct book or lecture series, you do not need to purchase it again.

If you do not already have it, you can purchase it from us in the same shopping cart when you enroll.

You can purchase the required book or lecture series directly from us when you enroll. Simply add the study materials you need to the same shopping cart as your Extension Course.

Books and lectures are available in multiple languages. If you would prefer a language other than English or Spanish, simply enter your preferred language in the order notes during checkout.

If you are located in Puerto Rico, your book and course pack will ship from our facility in San Juan.

If you are located elsewhere in the world, your materials will normally be drop-shipped from a regional distribution point near you, providing more practical international delivery.

Yes.

If you already own the required book or lecture series, simply enroll in the Extension Course without purchasing another copy.

Just make sure you have the correct material for the course you are taking.

Many books and lecture series are available in multiple languages.

We will arrange the appropriate language version when available.

Yes.

You may study from the appropriate authorized edition of the book or lecture materials in your preferred language while completing the online Extension Course in English or Spanish.

This can be particularly helpful for international students who prefer to study the source material in their native language.

No. We do not provide the course books as PDFs or e-books.

The required books and lecture materials are available in their authorized physical or recorded formats, depending on the title.

If you need the material in a language other than English or Spanish, enter your preferred language in the order notes when purchasing it from us.

The cost varies by course.

The current price for each Extension Course is displayed on its individual course page before you enroll.

Books or lecture materials are separate unless the course listing specifically states that they are included.

Your enrollment gives you access to:

• The online Extension Course and its lessons
• Personal review of your lessons by a human Extension Course Supervisor
• Individualized feedback on your submitted work
• Direct communication with your Supervisor through the in-app messaging system
• The physical Extension Course materials or course pack included with that particular course

The corresponding L. Ron Hubbard book or lecture series is purchased separately unless specifically stated otherwise.

Many Extension Courses include a physical course pack or other Extension Course materials.

If physical materials are included with your enrollment, they will be shipped to the address you provide during checkout.

Yes.

Students outside Puerto Rico can enroll in our Extension Courses, and physical study materials can be shipped internationally.

Rather than sending every international order from Puerto Rico, materials are normally drop-shipped from a regional distribution point serving your part of the world.

For students in Puerto Rico, books and course packs ship from our facility in San Juan.

For students elsewhere in the world, materials are normally fulfilled through a regional distribution point near the student.

The Advanced Clinical Courses, or ACCs, form a later portion of the Routes to Knowledge.

They contain L. Ron Hubbard’s lectures from periods of intensive research and development, along with related issues and writings from those periods.

The Extension Courses guide the student through these materials in sequence so that developments can be studied in the context in which they occurred.

The ACC Extension Courses correlate the lectures with related issues and writings from the same period.

This allows the student to follow the progression of the research and see how discoveries and developments relate to one another.

The lessons guide the student through the material step by step rather than treating individual lectures as isolated subjects.

Yes.

You are welcome to take an individual course that interests you.

You can also continue through the complete Extension Course route over time if you want to study the materials systematically.

Yes.

Once you complete a course, you can continue with another course or move to the next step in the recommended study sequence.

Your Extension Course Supervisor can help you determine the appropriate next course.

When you successfully complete all of the lessons on your Extension Course, you receive a certificate acknowledging your completion of the course.

You can then begin another book or lecture Extension Course or continue to the next step on your study route.

Your Course Supervisor can help you determine what to study next.

Yes.

Individual Extension Courses can be taken on their own, but they also fit together into the broader Routes to Knowledge.

This allows a student who wishes to do so to progress systematically through the books and lectures rather than selecting subjects at random.
