Institute for the Study of War Internship 2027–2028: How to Apply

Last updated: November 2026

The Institute for the Study of War (ISW) runs three intern cohorts a year, and its Spring 2027 cohort (January 12 to May 14, 2027) reviews applications on a rolling basis only until November 13, 2026, according to ISW's own postings. After that date, the next open door is summer 2027: we expect postings in early February 2027 and rolling review until about mid-April, based on the summer 2026 cycle. The internship is unpaid unless you win ISW's need-based scholarship, which pays up to $1,000 a month. In plain words: if you miss the November 13 spring cutoff, you apply between February and April 2027 and intern in summer 2027.

Quick Facts

The row that matters most: ISW reviews applications early and on a rolling basis, and each window lasts only about 10 weeks.

Externships are short, remote programs where you finish a real project for a real company, most often in 8 weeks at 5 to 10 hours a week. The Juvenile Justice Policy Analyst Externship with CIYJ builds the policy research and writing ISW asks for, and the vCISO Cybersecurity Risk Assessment Externship gives you a structured threat assessment to put in a writing sample.

What Is an Institute for the Study of War Internship?

An Institute for the Study of War internship is a full-time research or communications placement at ISW, a nonprofit policy research institute in Washington, DC that publishes open-source intelligence analysis on current conflicts and security threats. The program is one of three education programs in ISW's General David H. Petraeus Center for Emerging Leaders and is offered each spring, summer and fall. Interns start with an intensive two-week development program, attend weekly briefings, seminars and workshops, and can draft, edit and publish their own research. Several tracks work with the American Enterprise Institute's Critical Threats Project and Center for Defense of Taiwan on recurring updates. ISW publishes no class size or acceptance rate.

When Do Institute for the Study of War Internship Applications Open for 2027–2028?

ISW posts each cohort separately on its own BambooHR board. The summer 2026 postings went up February 2, 2026, review ran until April 17, and the program started June 2, so the lead time from posting to start was about 4 months. Fall 2026 followed the same shape. Its postings appeared between early May and early June 2026, and that cohort started September 8. The Spring 2027 tracks went up September 9 and 18, 2026, with review until November 13 and a January 12 start, which leaves each window open for roughly 10 weeks. We have one dated summer cycle, so the summer 2027 dates below are expected, not confirmed.

How to read this page: our dates come from tracking previous recruiting cycles and daily posting data. Treat them as informed estimates based on historical patterns, not confirmed dates. The company's official careers page is always the most current source. If a role is posted there, go by that, even if this page suggests the window hasn't opened yet.

Why You Must Apply the Week Applications Open

ISW's own FAQ says applications are reviewed on a rolling basis early in the cycle and tells candidates to submit as soon as applications open. Reviewers email selected candidates to schedule interviews while the window is still open, so a late application competes for fewer places. Each window runs only about 10 weeks, and ISW requires every intern to start on the stated start date. Have your writing sample, cover letter and, if you need it, scholarship letter ready before the summer 2027 postings go up in early February.

Which Institute for the Study of War Internship Programs Should You Target?

ISW runs one internship program in nine tracks. The table uses the Spring 2027 postings we read on November 12, 2026.

Summer 2026 used four broader tracks (intelligence analysis, Cognitive Warfare, Communications, Geospatial), so the summer 2027 list may differ. Read the ISW internships page before you apply.

What Are the Eligibility Requirements?

These come from ISW's internships page, its FAQ and the Spring 2027 postings, read on November 12, 2026.

• Who: motivated and organized college students or recent graduates. ISW's FAQ says there are no school-year or age eligibility requirements.

• Work authorization: you must be authorized to work in the US, which ISW says includes US citizens and those with CPT/OPT authorization, and F-1 students must obtain CPT before starting. No citizenship or clearance requirement is stated.

• Location: you must be in the US for the whole internship.

• Start date: fixed for everyone. All selected interns must start on the stated start date, so plan exams, travel and CPT paperwork around it.

• Background: ISW says prior experience in foreign and defense studies isn't necessary.

• GPA: not stated.

Do You Need a Foreign Language?

For the six research tracks, a language is a strong plus: each posting asks for critical language skills tied to its region, such as Mandarin, Korean, Russian, Ukrainian, Arabic or Farsi. ISW's FAQ says reviewers look for proven critical language skills, regional knowledge and experience, and professionalism. The Geospatial, Communications and Multimedia tracks don't list a language. Put your proficiency level on your resume.

What Skills Does the Institute for the Study of War Look For, and How Do You Build Them?

We read all nine Spring 2027 postings in full. Writing is the one constant: seven ask for "excellent writing, editing, and oral communication skills" in those words, and the other two ask for writing and editing in different phrasing. Eight ask you to be self-motivated and able to work in a fast-paced setting. The six research tracks ask for a regional language and describe daily open-source collection. The technical asks are track specific: GIS software, SQL and Arcpy for Geospatial, Python on the Middle East track, Adobe Premiere Pro for Multimedia and AP or Chicago style for Communications.

No open Externship teaches a foreign language or GIS. These cover the writing, analysis, data and communications side of the postings.

What Is the Institute for the Study of War Application and Interview Process Like?

ISW describes a direct application and an interview stage in its postings and FAQ.

1. Choose a track. Each track has its own posting on ISW's BambooHR board, linked from the careers page.

2. Upload three documents. Resume, cover letter and writing sample. The cover letter and writing sample together can't run past five pages, and the sample can be an excerpt.

3. Add the scholarship application if you need it. It's a separate upload: a 2 to 3 page letter that answers ISW's set questions, including on financial need.

4. Interview. You get a confirmation email, and reviewers email selected candidates to schedule interviews.

5. Decision. Interviewees receive a finalist or waitlist notice. ISW publishes no decision dates.

What Students on Reddit Say

We found little first-hand discussion of ISW's internship on Reddit. The one usable thread is a timing report, lightly paraphrased below.

How Do You Stand Out for an Institute for the Study of War Internship?

First, apply in the first days of the window, since ISW reviews early and on a rolling basis. Second, lead with your language: list each language and your proficiency level, and add relevant coursework and study abroad under Education, as ISW's FAQ suggests. Third, choose your writing sample with care, because it's the clearest proof you can do the work. A tight, sourced excerpt on a region or security topic shows the analytical writing every posting asks for. ISW's FAQ also says not to drop retail or restaurant jobs, because they show professionalism. ISW publishes no applicant count or conversion rate, but says it has hired many interns onto its staff.

FAQ

Can I still apply for a summer 2026 Institute for the Study of War internship?

No. The summer 2026 program ran June 2 to August 21, 2026, and its review ended April 17. ISW's Spring 2027 cohort reviews applications only until November 13, 2026. After that, the next window is summer 2027, with postings expected in early February 2027 and review until about mid-April.

When do ISW internship applications open?

Three times a year, about four months before each cohort starts. Spring 2027 posted September 9, 2026 and closes November 13. Summer 2027 postings are expected in early February 2027, based on summer 2026, which posted February 2. Fall postings appeared between early May and early June in 2026.

Is the ISW internship paid?

Not by default. ISW's postings list compensation as scholarships available by application. Its need-based scholarship pays up to $1,000 a month as a living stipend and counts as taxable income. You apply for it with a separate letter at the same time as the internship. ISW also helps students get academic credit where appropriate.

Can I do an ISW internship remotely?

Yes, from inside the US only. ISW offers remote, hybrid and in-person internships at its Washington, DC office, but it can't host interns working from outside the United States. You must be in the US for the whole internship, and all interns start on the same fixed start date.

Do I need to be a US citizen for an ISW internship?

No citizenship requirement is stated. You need US work authorization, which ISW says includes US citizens and those with CPT or OPT authorization. Students on an F-1 visa must be eligible for and obtain CPT before they start. The postings we read don't mention a security clearance.

Do I need a foreign language for an ISW internship?

For the six research tracks, a regional language is strongly preferred, such as Mandarin, Korean, Russian, Ukrainian, Arabic, Hebrew, Turkish, Kurdish or Farsi. The Geospatial, Communications and Multimedia tracks don't ask for one. ISW says prior experience in foreign and defense studies isn't necessary for any track.

How long is the ISW internship?

About 12 to 18 weeks, depending on the cohort. Spring 2027 runs January 12 to May 14, 2027, and summer 2026 ran June 2 to August 21. Internships are full time, five days a week, and ISW considers part-time schedules case by case. Every cohort starts with a two-week development program.

Does ISW hire its interns?

Sometimes. ISW says it has hired many interns onto its staff, and its internships page features former interns who joined as researchers and associates. It doesn't publish a conversion rate. Graduates can also apply to ISW's separate fellowships, which are for people after college, not current students.

If you miss the spring cutoff, use the months before February to prepare for summer 2027. A remote Externship gives your cover letter and writing sample a finished policy or analysis project to describe.
