I used the EDGE Clinical Nutrition Study guide for my CNSC re-certification, it was so helpful in focusing on what needs to be reviewed for the exam! I felt very prepared going into the exam and felt that the study guide captured the majority of the testing material. There is also a guided study group tailored to first-time test takers, I did not follow this as I was taking as a re-cert, but I wish it had been around when I first took the exam.
I purchased the CPE Nutrition Support Course first and got so interested I bought the CNSC study guide – and passed on my first try. HIGHLY recommend both resources for RDs to fully comprehend EN/PN.
Edge Clinical Nutrition Study Guide was extremely helpful! I am already a CNSC and found her guide beneficial in my recertification. The quizzes, videos and guide were organized, detailed and pertinent for the exam. Sara is also very kind and quick to answer questions when you reach out to her.
I recently used the Edge Clinical Nutrition CNSC Study Guide to prepare for the CNSC exam and passed. Even though I have worked in nutrition support for many years, I found the guide to be a really helpful way to organize my studying and make sure I was reviewing all of the major content areas covered on the exam. The study materials were easy to follow, and I especially appreciated the practice questions, which helped me identify areas where I needed additional review. What I liked most was having a structured study plan. Preparing for the CNSC can feel overwhelming because there is so much information to cover, and the guide helped me stay focused and efficient with my study time. I would highly recommend the Edge CNSC Study Guide to anyone preparing for the exam, whether you are newer to nutrition support or simply looking for a comprehensive review before testing. It was a valuable resource and an important part of my preparation.
Sara’s resources were incredibly helpful for taking the CNSC exam. She explains tough concepts in an approachable way and guides students through the daunting exam process. Highly recommend!
Excellent CNSC study resource! Sara is always very responsive with any questions that come up. Well-structured, thorough, and easy to navigate. It helped reinforce important concepts and made studying more efficient. Highly recommend for anyone preparing for the CNSC exam.
I am currently enrolled in the nutrition support course and am planning on doing the CNSC course for this upcoming fall! From what I’ve experienced so far, the binders, webinars and other materials offered with each section helped me improve my knowledge and I even use it in practice! Sara is also very easy to communicate with!
