  • Can I enroll in the program at any time?

    Yes! We admit students on a rolling basis, and you will automatically be added to the next available term once you've successfully enrolled.

  • Once I am enrolled, when does the content become available?

    When you enroll, you are automatically added to the next available term. Every term has a fixed start date, and content becomes available on that date.

  • Can I enter the classroom prior to the start of my term?

    Yes, but you won't be able to access the content, as it stays locked until your term begins. In the classroom, you'll see a countdown to your term's start date.

  • Are deferments an option if I'm enrolled, but not ready to start yet?

    No, deferments are not an option. We ask that you please make sure to enroll for a term only if you are able to commit to the entire time frame.

  • Is payment due before the term begins?

    Yes. In this way, we know exactly how many student are in a term, and can optimize our instructional and support resources accordingly. Additionally, this approach ensures a consistent and stable student body throughout the program, which fosters a deeper sense of community, and enables richer collaborations as students work together as a group.

  • Can I enroll in other Nanodegree programs while I'm enrolled in the Machine Learning Nanodegree program?

    Our programs require a serious time commitment from students, so while we do not recommend doing so, we do not prohibit concurrent enrollments. This is an intensive, paced program, and students must proceed throughout the programs at the required rate of progress. To make the most of your experience, we believe you are best served by focusing on one program at a time and being fully immersed in the unique structure and pacing. You can always take one after the other!

  • Will I have access to the material even after the term ends?

    No. You will retain access to the program materials for a period of time after graduation and you may download certain materials for your own records if you wish. Please note however, that students who leave the program—or who are removed from the program for failure to meet deadlines—prior to successfully graduating, will cease to have access.


  • How much does the Nanodegree program cost?

    This Nanodegree program consists of one term that is six months long. Students must complete the full six months to earn their credential and graduate. The term costs $999, which is paid at the beginning of the term.

  • Is there a free trial period for this program?

    No, there is no free trial period for this program.

  • What is the refund policy?

    There is a 7-day refund policy. During this time, you can visit the Settings page of your Udacity classroom where you can unenroll and request a full refund. This 7-day window begins the day the classroom opens. After the first 7 days, course fees are non-refundable.

  • Are there any scholarships available for this program?

    All current scholarship opportunities are posted on our Scholarships page.

Structure & Deadlines

  • How many hours a week should I expect to spend on my coursework, in order to succeed in this program?

    Between instructional content, quizzes, projects, and other course-related activity, we estimate that investing 15 hours per week will enable you to proceed through the program at a successful pace.

  • Is this program self-paced?

    It is not. This is a unique, termed program that requires students to keep pace with their peers throughout the duration of the program. If a student does not complete a term by the term deadline, they will be removed from the program and will need to re-enroll in a new term and pay the full term fee in order to continue.

  • Will I be able to pause my Nanodegree program?

    No. Due to the fixed-term nature of the Machine Learning Nanodegree program, and the need for maintaining a consistent and stable student body throughout, it will not be possible to pause your enrollment in this program.

  • What happens if I don't complete a project on time?

    It is strongly recommended that you complete each project on time to ensure you meet graduation requirements. To graduate, you must complete, submit, and meet expectations for all required projects within six months of your start date. While there is no penalty for missing a project deadline, missing one puts you at risk to be removed from the program if you do not stay on track and complete all required projects before the term ends. Finally, by keeping pace with your fellow students, you'll gain much more value from forums and Slack channels!

  • What happens if I don't complete a term by the term deadline?

    You will receive a free four-week extension, which is automatically applied to your account if you do not complete the term within the allotted six-month timeframe. If you do not complete the term within the extension, you will be removed from the program and will no longer be able to access course content. To resume access to the course, you would need to pay the term fee again. Your progress would carry over, so you would be able to continue where you left off.


  • Will content from the program also be available for free outside of the Nanodegree program?

    While some of the video material is available outside of the program, most of the material will only be available to currently enrolled Nanodegree students. Access to project feedback, instructor support, and hiring partners are benefits exclusive to the Nanodegree programs.

  • Will there be Udacity Connect sessions held for this Nanodegree program?

    Yes! We are happy to offer Udacity Connect for Machine Learning students in certain select locations including the San Francisco bay area. You are welcome to apply through the Udacity Connect page.
