Cornerstone Research application deadlines 2027: Summer Analyst closes September 27
Cornerstone Research's US Summer Analyst deadline is September 27, 2026, stated on the firm's postings across multiple university careers boards.12 A secondary deadline follows in mid-October, but the firm strongly recommends the primary date.3 The program targets undergraduate juniors graduating December 2027 to June 2028, and successful applicants typically have a GPA above 3.6.1
Cornerstone Research's primary Summer Analyst deadline of September 27, 2026 has passed. A secondary deadline typically follows in mid-October, though the firm strongly recommends the primary date.3 Check the firm's recruiting events calendar for current dates, and note that the next cycle's primary deadline is expected in late September.5
Cornerstone runs a primary and a secondary Summer Analyst deadline. In the prior cycle these were September 21 and October 12, and the firm stated it strongly recommends applying by the primary date to be considered for the role.3 Treat the secondary deadline as a fallback rather than a plan.
A published date, and a second chance behind it
Cornerstone Research is unusual at this tier: it publishes a firm deadline. US applicants are told to submit through the online portal by September 27, 2026 for consideration, a date carried identically on multiple university careers boards.12
What is less well known is the two-stage structure. In the prior cycle the Summer Analyst primary deadline was September 21 with a secondary deadline of October 12, and the firm strongly recommended applying by the primary date to be considered for the role.3
| Role | Who it is for | Deadline | Status |
|---|---|---|---|
| Summer Analyst | Undergraduate juniors, graduating December 2027 to June 2028 | September 27, 2026 | |
| Summer Analyst, secondary | Same | Expected mid-October 2026 | Expected |
| Analyst, full-time | Graduating seniors | Historically late September | Expected |
| First-Year Foundations and Sophomore Summit | First and second year undergrads | Hosted 2027, watch events calendar | 2027 |
In prior cycles the full-time Analyst deadline landed a week before the Summer Analyst one, on September 24 versus October 1 in one documented year.4 If you are eligible for both, the full-time date is the one more likely to catch you out. Cornerstone directs candidates to its recruiting events calendar for all application deadlines.5
The GPA bar is the highest in this set
Cornerstone states that successful applicants typically have a GPA higher than 3.6, alongside demonstrated strong academic performance and strong analytical backgrounds through academics or internships.1
There is no officially published hard minimum, but 3.6 out of 4.0 is the de facto bar and it signals how selective the pool is.6 That is meaningfully above the 3.0 to 3.3 range typical across the Big 4 consulting tracks.
The good news is what is not required. All majors and fields of study are welcome, quantitative fields such as mathematics, statistics, computer science and physics are well suited but no specific major is required, and prior economic consulting experience is explicitly not needed.6 The firm states directly that you need not be deeply familiar with the industry before applying, because that is what the program is for.1
Case teams here include an academic expert
Summer Analysts work on case teams that typically include a faculty or industry expert, senior consultants and analysts, contributing to financial and economic analyses and helping prepare experts for testimony. The analytical rigor overlaps with strategy casing even though the work differs. Our case library has full cases with exhibits and worked solutions.
Free cases available without an account.
What the program actually is
The Summer Analyst Program is an eight-week experience taking place in the summer between your junior and senior year, opening with a three-day orientation designed to get you productive quickly.15
The role closely mirrors the full-time analyst position. You join case teams that typically include an expert, senior consultants and analysts, contribute to financial and economic analyses, help prepare experts for testimony, and present findings to colleagues, experts and clients.17
Many Summer Analysts choose to join Cornerstone Research full time upon graduation, and the internship is the primary entry point into consulting at the firm.15
Why this firm deserves more attention than it gets
Cornerstone Research's Summer Analyst Program ranked fifth on Vault's 2026 Best Consulting Internships list and fourth for finance, and the firm partners with top academics from Stanford, Harvard and MIT on high-stakes litigation.6
Economic consulting is a genuinely different career from strategy consulting, with heavier quantitative work, litigation exposure and strong graduate school placement. If you are considering a PhD or law school after two or three years of work, this path is worth more consideration than the volume of online coverage suggests.
One practical note: visa sponsorship policies are not publicly detailed for summer analysts, and interns typically work on Curricular Practical Training authorization.6 Ask the recruiter directly rather than assuming.

- Target September 27, not the secondary date. The firm recommends the primary deadline explicitly.
- Check the recruiting events calendar for your campus, since Cornerstone points candidates there for all deadlines.
- Be honest about the GPA bar. Above 3.6 is typical, which is higher than most of the firms on this site.
- Do not worry about your major. All fields are welcome and prior industry knowledge is not required.
