Caltech\u2019s 2026-2027 Prompts<\/h2>\n\n\n\n

Required STEM Academic Interest Question<\/h3>\n\n\n\n
    \n
  1. Caltech has a rigorous core curriculum<\/a> and students don’t declare a major until the end of their first year. However, some students arrive knowing which academic fields and areas already most excite them, or which novel fields and areas they most want to explore. If you had to choose an area of interest or two today, what would you choose? Why did you choose your proposed area of interest? If you selected ‘other’, what topics are you interested in pursuing? (150-200 words)<\/em><\/li>\n<\/ol>\n\n\n\n

    Scholarly Character (Choose One)<\/h3>\n\n\n\n

    Caltech introduces this pair with a question: \u201cHow do you learn when there is no easy answer?\u201d Choose one<\/strong> of the following prompts. Each response has a limit of 200 words.<\/p>\n\n\n\n

      \n
    1. Option 1 – Collaboration:<\/strong> Tell us about a time your learning in STEM was shaped by another person or group, either because you needed help, offered help, changed your thinking through collaboration, or contributed to someone else’s understanding. What did that experience teach you about learning and working with others?<\/li>\n\n\n\n
    2. Option 2 – Process:<\/strong> Tell us about a time your approach to a STEM problem, concept, or project mattered as much as the outcome. How did you work through uncertainty or persist creatively in tackling the problem? What would you still defend about your process, regardless of the outcome?<\/li>\n<\/ol>\n\n\n\n

      Scientific Drive (Choose Two)<\/h3>\n\n\n\n

      Caltech introduces this set with another question: \u201cHow does STEM come alive in your life through learning, pursuing, or making?\u201d Choose two<\/strong> of the following prompts. Each response has a limit of 200 words.<\/p>\n\n\n\n

        \n
      1. Option 1 – Learning:<\/strong> Regardless of your STEM interest listed above, take this opportunity to nerd out and talk to us about whatever STEM rabbit hole you have found yourself falling into. Be as specific or broad as you would like.<\/li>\n\n\n\n
      2. Option 2 – Pursuing:<\/strong> Tell us about a STEM question, problem, idea, or project that has held your attention over time. What drew you to it, how have you pursued it, and what do you still want to understand?<\/li>\n\n\n\n
      3. Option 3 – Making:<\/strong> Tell us about something you created, tested, repaired, modeled, coded, built, or redesigned. What problem were you trying to solve and what did the process reveal to you?<\/li>\n<\/ol>\n\n\n\n

        Fun Question<\/h3>\n\n\n\n
          \n
        1. Caltech students bring more than academic ability to the communities they join. What is something you would be excited to do, share, teach, make, start, or contribute as part of the Caltech community? (100-150 words)<\/em><\/li>\n<\/ol>\n\n\n\n

          Optional Academic Short Answer Question<\/h3>\n\n\n\n
            \n
          1. Caltech cares about context. Is there anything about your academic preparation, coursework, school context, or learning experiences that would help us better understand your readiness for Caltech?<\/li>\n<\/ol>\n\n\n\n

            General Tips<\/h2>\n\n\n\n

            While Caltech is unusual in offering eight essay prompts for applicants to answer, these essays don\u2019t have to be difficult. Before you begin writing the first essay, read through all the prompts. That way, you can pace yourself. If a topic has multiple facets that could be discussed in different essays, versus getting jammed into one essay, then go for it. What might seem like an excessive number of essays to write is actually just an abundance of opportunities to show Caltech who you are.<\/p>\n\n\n\n

            Moreover, the optional essay prompt is really just that: optional. In order to be effective and boost your chances of admission, your Caltech supplemental essays need to be thoughtful, organized, proofread, and specific. If you only have the bandwidth to bring your best writing talents to the required prompts, you should feel no pressure to write one more rushed essay. In addition, the optional prompt won\u2019t relate to all applicants. In other words, don\u2019t try to write a response to the optional prompt if it doesn\u2019t speak to you. Instead, consider all of the parts of yourself you\u2019d really like Caltech to know, and do your best to incorporate them into the essays you are required to write.<\/p>\n\n\n\n

            That said, let\u2019s dive in.<\/p>\n\n\n\n

            Caltech Required STEM Academic Interest Question<\/h2>\n\n\n\n

            Caltech has a rigorous core curriculum and students don’t declare a major until the end of their first year. However, some students arrive knowing which academic fields and areas already most excite them, or which novel fields and areas they most want to explore. If you had to choose an area of interest or two today, what would you choose? Why did you choose your proposed area of interest? If you selected ‘other’, what topics are you interested in pursuing? (150-200 words)<\/em><\/h3>\n\n\n\n

            Although you\u2019re not bound to study whatever major or area of interest you describe in this essay, you should answer authentically. Through the Caltech supplemental essays, the admissions team seeks curious, driven individuals who already know they want to pursue STEM. Because of this, you\u2019ll want to let your passion shine through.<\/p>\n\n\n\n

            In addition, whether you have a particular origin story behind your academic interest(s), or you simply enjoy pursuing the questions behind your interest(s), this essay response will benefit from specific details. For example, you hope to study computer science, explain to the reader what kind<\/em> of computer science you\u2019re interested in, how you became interested in this subfield, and, if you have space, what you hope to do with this degree. Don\u2019t be afraid to sound nerdy!<\/p>\n\n\n\n

            Caltech Scholarly Character Essays<\/h2>\n\n\n\n

            Caltech frames this pair of prompts with a question: \u201cHow do you learn when there is no easy answer?\u201d You\u2019ll answer one of the two options below in 200 words or fewer. Both options are getting at the same underlying trait, a willingness to keep working when the answer isn\u2019t obvious, so choose the option that comes with your most specific story rather than the one that sounds more impressive.<\/p>\n\n\n\n

            Option 1 – Collaboration: Tell us about a time your learning in STEM was shaped by another person or group, either because you needed help, offered help, changed your thinking through collaboration, or contributed to someone else’s understanding. What did that experience teach you about learning and working with others? (200 words or fewer)<\/em><\/h3>\n\n\n\n

            This option asks you to think about STEM as something you do with other people. Notice how broad the prompt is: you could write about needing help, offering it, changing your mind because of a collaborator, or helping someone else finally understand a concept. Whichever direction you choose, admissions officers want to see that you can learn from and alongside others, because that is how learning works at Caltech, where the core curriculum is famously demanding and students lean on one another to get through it.<\/p>\n\n\n\n
