Lambda School features and specs

  • Income Share Agreement
    Lambda School offers an Income Share Agreement (ISA), allowing students to defer tuition payments until they secure a job making at least $50,000 per year. This reduces upfront financial risk for students.
  • Remote Learning
    The program is entirely online, providing flexibility for students to learn from anywhere in the world.
  • Comprehensive Curriculum
    Lambda School offers a comprehensive curriculum that covers a wide range of in-demand tech skills, including web development, data science, and machine learning.
  • Career Services
    The school provides extensive career services, including job placement support, resume reviews, and interview preparation to help students secure employment after graduation.
  • No Upfront Cost
    Students can enroll without any upfront cost, making the program accessible to those who may not have the financial means to pay for a traditional coding boot camp.

Possible disadvantages of Lambda School

  • High Deferred Cost
    Although there are no upfront costs, the total cost of the ISA can be high, potentially up to $30,000, which is more expensive than some other coding boot camps.
  • Intensive Time Commitment
    The program is very intensive and requires full-time dedication, which can be challenging for individuals who need to balance other responsibilities such as work or family.
  • Variable Job Market
    Job placement success can vary significantly. While many students do find jobs, some may struggle, particularly in a competitive job market.
  • Risk of Debt
    If a student does not secure a high-paying job immediately, the deferred tuition can become a financial burden, particularly if the student is unable to make the minimum required salary.
  • Limited Financial Assistance
    Since the program relies heavily on ISAs, there may be limited options for students seeking traditional financial assistance or loans.

Lambda School mentions (19)

  • Switching careers
    Https://lambdaschool.com/ - a remote-first bootcamp that has a unique way of paying. No upfront cost, but they take a % of your salary when you get a job for the first two years until you pay their full cost. Worth reading up on some of the criticism of them before signing up, though. Source: almost 5 years ago
  • LF a Certification Program
    Https://lambdaschool.com/ (these guys offer a free intro, might be good to test out and see if their style is to your liking.). Source: almost 5 years ago
  • Advice for a nurse that wants to become a programmer
    While you don't need a boot camp, I highly recommend Lambda School (https://lambdaschool.com). They charge nothing upfront and you only pay them back (17% up to $30k) when you get a high paying job. They have great partnerships with employers and help place students so that's the biggest reason I recommend them. Source: almost 5 years ago
  • Been really poor, homeless, now Iโ€™m in college and have managed to save up 3000. I want to turn this money into more money. What would you do?
    Have you considered https://lambdaschool.com/? You don't pay for tuition upfront, and they place you with a paid internship after, and if you get a job you start paying a small part of your salary to them for two years. Source: almost 5 years ago
  • Late 20โ€™s, no education, some savings, should I work full time and save a bit more or start school?
    Would you consider going through a school with an Income Share Agreement where you pay no tuition up front but pay it as part of your well paying job later? Eg https://lambdaschool.com. Source: almost 5 years ago
