Mechanical Engineering — "Course 2" in MIT's numbering system — is one of MIT's founding disciplines and remains one of its most popular majors, spanning everything from robotics and mechatronics to thermodynamics, materials, and biomechanics. It sits alongside EECS as one of MIT's flagship engineering programs, and its graduates go on to build hardware at companies ranging from aerospace giants to robotics startups to the automotive industry's electrification push. For applicants who want MIT's hands-on "mind and hand" engineering culture applied to physical systems rather than pure software, Mechanical Engineering is arguably the most representative MIT department there is.
This guide covers the acceptance rate reality, cost, admission requirements, how to get in, English-test rules, and career outcomes specific to MIT Mechanical Engineering, at both the undergraduate (SB, Course 2) and graduate (SM/PhD) level.
Acceptance Rate: What MIT Actually Publishes
MIT does not publish a department-specific acceptance rate for Mechanical Engineering. Here's the honest, grounded picture:
- MIT undergraduate (institute-wide): 4.6% for recent classes. As with every MIT major, there is no separate admissions process or acceptance rate for Course 2 — all first-years are admitted to MIT as a whole and declare their course at the end of first year. Mechanical Engineering is consistently one of MIT's most-declared majors (alongside EECS), so it draws from a very strong and large slice of the admitted class, though it is generally understood to be somewhat less oversubscribed at the declaration stage than Course 6 (EECS).
- MIT graduate (institute-wide): roughly 9% across all departments. Mechanical Engineering's SM/PhD programs are highly competitive but not typically considered as singularly oversubscribed as EECS; a reasonable, unofficial estimate for a strong, traditional engineering department of MechE's caliber and size at MIT would put it in a similar single-digit-to-low-double-digit range as the institute average, though MIT publishes no confirmed figure.
- International undergraduate applicants overall face a much tighter effective rate (MIT reports around 2% for international applicants in a recent cycle across all majors combined), which applies to prospective MechE students as much as any other intended major.
Bottom line: no MIT source breaks out a Mechanical Engineering-specific acceptance rate at either level. Treat the institute-wide 4.6% (undergraduate) and 9% (graduate) figures as the best available anchors, with the understanding that MIT's overall selectivity applies broadly across its strongest engineering departments.
Fees and Cost of Attendance
MechE follows MIT's standard, uniform tuition schedule — the same regardless of department or citizenship:
| Cost Item | Undergraduate (USD/year) | Graduate (USD/year) |
|---|---|---|
| Tuition | $66,720 | $66,720 |
| Living expenses | $25,620 | $42,297 |
| Total estimated cost of attendance | $92,760 | $109,017 |
MechE graduate students pursuing a PhD are typically fully funded (tuition, stipend at the standard MIT doctoral rate — approximately $51,226/year as of the 2025-26 cycle — plus health insurance), usually through a mix of fellowship funding in the early years and research/teaching assistantships later. SM (master's-only) MechE students generally are not guaranteed this funding and should budget for the full cost of attendance unless they secure a specific research assistantship or fellowship. Application fees are $75 (undergraduate) and $90 (standard graduate), with fee waivers available for financial hardship.
Admission Requirements
Undergraduate (declared as Course 2 after first year):
- Common Application or Coalition Application
- MIT-specific short-answer questions and essays
- Secondary school transcript
- SAT or ACT scores — mandatory for all applicants, domestic and international
- Two letters of recommendation (one math/science, one humanities/language/social science teacher)
- School report and counselor recommendation
- English proficiency test scores (recommended, not mandatory, for non-native speakers)
- $75 application fee or fee waiver
Middle-50% test ranges for admitted MIT students: SAT 1520-1580, ACT 34-36. MechE applicants specifically are expected to show strong physics and math preparation, and hands-on evidence of building or designing (robotics competitions, maker projects, engineering-focused extracurriculars) is a well-known differentiator for engineering-track applicants at MIT.
Graduate (SM/PhD in Mechanical Engineering):
- Online application via GradApply/GradSlate
- Unofficial transcripts from all institutions attended
- Three letters of recommendation
- Statement of Objectives / Personal Statement
- Updated CV/resume
- GRE/GMAT: not university-wide required; policy is department-specific, so confirm directly with the MechE department for the current cycle, since STEM departments at MIT have moved in different directions on this in recent years
- English proficiency test scores, required for most international applicants unless a waiver applies
- $90 application fee or fee waiver
MechE's graduate application deadline generally follows MIT's typical early-December window, with decisions released February-March.
How to Get In
-
Undergraduate: pair strong physics/math grades with tangible hands-on evidence. MechE admissions readers (via MIT's holistic institute-wide process) respond strongly to applicants who have actually built and iterated on physical things — FIRST Robotics, a personal fabrication project, a documented engineering competition — rather than only excelling in coursework.
-
The SAT/ACT is mandatory — treat it as a floor, not a differentiator. Since MIT reinstated standardized testing for everyone, a score near the 1520-1580 SAT range is table stakes; a weak score is a real liability precisely because nearly all other applicants will clear it comfortably.
-
Graduate applicants: identify specific MechE labs and faculty. MIT's MechE department spans a very wide range — from robotics and controls to thermodynamics, ocean engineering-adjacent work, and biomechanics — so a Statement of Objectives that names specific labs and open problems the applicant wants to work on reads far stronger than a generalized "I love mechanical engineering" pitch.
-
Confirm the current GRE policy before you invest prep time. Because MIT does not mandate GRE institute-wide and STEM departments vary in their stance, check MechE's current admissions page directly rather than assuming based on EECS or another department's policy.
-
For PhD applicants, prior research experience is close to essential. MechE PhD admissions are research-driven; a strong track record of undergraduate research (a thesis, a publication, or substantial lab experience) with recommenders who can speak to independent research capability matters more than coursework alone.
English Proficiency Requirement (IELTS/TOEFL)
MechE follows MIT's university-wide English-proficiency policy rather than a department-specific one:
- Undergraduate: no English test is required at all — only "strongly recommended" for applicants who have used English for fewer than 5 years or don't use it at home/school. If submitted, MIT's published thresholds are IELTS minimum 7.0 (recommended 7.5) or TOEFL minimum 90 (recommended 100).
- Graduate: the Office of Graduate Education (OGE) sets a recommended floor of IELTS 7.0, TOEFL iBT 100, or Duolingo 135 for essentially all international applicants, though individual departments can set (and enforce) stricter minimums that supersede this general floor. PTE is not accepted for MIT graduate admissions.
- Waiver: generally available for applicants with a 3-4+ year undergraduate degree from an English-medium institution completed within the last 5 years, or native English speakers.
MechE has not published a department-specific override to the OGE floor, so applicants can generally treat the university-wide numbers as applicable, but should still confirm on the MechE graduate admissions page for the current cycle, since the OGE explicitly states department minimums take precedence where published. For full detail on MIT's testing policy across levels, see MIT IELTS requirements and MIT TOEFL requirements.
Career Outcomes
MIT does not publish MechE-specific outcomes data, but as one of MIT's flagship, historically strongest engineering departments, MechE graduates track closely with — and in some sectors (aerospace, robotics, advanced manufacturing, automotive) may exceed — the university-wide figures:
- Undergraduate employment rate after 6 months: ~92%
- Undergraduate average starting salary: ~$118,100 (university-wide; MechE graduates entering aerospace, robotics, automotive, and hardware engineering roles are typically in a comparable or higher range depending on sector and location)
- Graduate average starting salary: ~$173,132 (university-wide graduate figure)
- Top recruiters: Google, Amazon, Microsoft, Apple, Bloomberg, Boston Consulting Group, McKinsey & Company, Citadel and Citadel Securities, Accenture, and Databricks feature among MIT's overall top recruiters, with Mechanical Engineering graduates specifically also heavily recruited by major aerospace and defense firms, automotive and EV companies, robotics startups, and advanced manufacturing and industrial design firms not captured in the university-wide list
MechE's breadth — spanning software-adjacent robotics and controls work through to traditional heavy industry and energy systems — gives its graduates an unusually wide range of exit paths, from Silicon Valley robotics startups to established aerospace primes to further graduate study.
