Make learning fun!
Say goodbye to boring slide decks and dense textbooks and start your journey to passing the CNSC Exam with my dynamic, holistic approach designed for the modern learner
Learn from an educator and nutrition support expert
Developed by a seasoned nutrition support expert, educator, and 2-time CNSC
How does this compare to other study guides out there?
Other CNSC exam study guides rely on PDFs, case studies, and slide decks alone. My dynamic educational approach focuses on holistic, student-centered learning. I provide a physical study guide that you can take notes on and study off a computer screen, plus practice exams, flashcards, video lectures, and even a group study session for last-minute exam prep.
I have precepted dozens of interns and won awards for my precepting work, including a feature in Sodexo's magazine and Colorado Dietitian of the Year award. I have a Master's Degree in nutrition with an emphasis on education, and I taught college nutrition for five years. My approach works!
My structured study guide approach
My study guide is not simply a "Cliff Notes" version of the ASPEN Core. In fact, because the ASPEN Core is organized so differently from the CNSC Exam Content Outline, relying on this alone will likely leave gaps in your studying.
For example, the ASPEN Core has a lot of emphasis on carbohydrates and very little emphasis on ethics, whereas the CNSC Exam has a lot of emphasis on ethics and very little content on carbohydrate metabolism.
My 80-page study guide provides detailed explanations of all 51 Content Domain and Task Statements, so you don't miss a single thing.
“I got [another study guide], but I got frustrated because it was basically just a statement based without explanation/rationale. I need to know the reasoning and explanation in order to tie everything together...while there was a lot of content, it didn’t support my actual understanding of the processes. I really appreciate your modules, occasional videos, supplemental info, and Quizlet. It feels more like a course vs “here’s all the info, now figure it out yourself”. Also your printed binder is much appreciated!!!” - 2025 study guide student
Don't settle for an incomplete study guide filled with statement-based material that still requires you to do your own research, reasoning and rationale to tie it all together.
This is for you if...
✅ You feel overwhelmed by the exam and need a study guide that simplifies complex concepts and saves you time.
✅ You understand that a "Cliff notes version" of the ASPEN core won't cut it, and you want to ensure you study the entire NBNSC Content Domain & Subtask outline, so you don't miss a single area.
✅ You're sitting for your 5-year recertification, and want to maximize study time and ensure you pass.
✅ You're taking your recertification, but you've been working in a niche area for the past few years, and you're worried about exam content you haven't touched in a long time.
✅ You need current, up-to-date practice exams.
✅ You don't remember a thing from your statistics class!
✅ You want to know what not to study, so you don't waste your time.
This is NOT for you if...
❌ You are not yet qualified to take the CNSC Exam and need more foundational knowledge in clinical nutrition [grab this freebie to find out if you're ready to start studying for the CNSC Exam].
❌ You are not yet fluent in tube feeding and parenteral nutrition (PN) calculations and can't write a tube feeding or PN order on your own [check out my Nutrition Support Skills Course].
❌ You’re looking for a free, basic resource and aren’t willing to invest in a comprehensive study guide that’s designed to save you time.
❌ You prefer a slow-paced, one-size-fits-all study approach and don’t want the flexibility to study at your own pace.
❌ You prefer traditional, dense textbooks and don't mind spending countless hours wading through irrelevant material.
❌ You're not planning to work in clinical nutrition, and don't need resources for your job.
