What Do You Need for an Internship? The Complete 2026 Checklist

What do you need for an internship? The short answer

If you are a student, you rarely need prior work experience to land an internship. You do need to show that you are reliable, teachable, and genuinely interested in the field. Concretely, most internship applications require:

Beyond paperwork, you need three qualities that no document can replace: a genuine interest in the work, basic reliability (showing up, meeting deadlines, communicating), and the willingness to learn on the job. Employers rank these above grades in most hiring decisions for entry-level roles.

Application documents you need

The exact document list varies by employer, but the following items cover the vast majority of internship applications in 2026.

CV or resume

Your resume is the first thing a recruiter reads. For most student internships, keep it to one page and structure it around education, relevant coursework, projects, and any part-time work or volunteering. Use action verbs and quantify results where possible (for example, "managed a 40-member student society budget" rather than "was a society member"). Academic research internships often prefer a longer CV with publications and presentations. If you are unsure where to start, our CV writing guide and resume templates walk you through it.

Cover letter

A cover letter is where you connect the dots between your background and the specific role. Keep it under one page, address it to a named person if possible, and answer three questions: who you are, why you are interested in this organization, and why they should pick you. Use our internship cover letter guide for a full structure and samples.

Transcripts and proof of enrollment

Many employers, especially for academic and research internships, ask for official or unofficial transcripts. Some require a letter from your university confirming your student status. Order these early: transcripts can take two to three weeks to arrive.

References

Choose two or three people who know your work directly: a professor, a club advisor, or a previous employer. Ask them well in advance, remind them a week before the deadline, and never list someone without permission.

Portfolio and work samples

For design, writing, marketing, and programming roles, a portfolio often matters more than the resume. Include three to five of your best pieces with a one-line caption for each covering your role, the tools used, and the outcome. For developers, a public GitHub profile with clean, documented projects is standard.

ID and work authorization

Paid internships require you to legally work in the host country. In the USA, F-1 students typically need CPT or OPT authorization. In the UK and most of Europe, your student visa either permits limited work or you need a separate arrangement. Check with your university's international student office before applying for paid roles.

Qualifications and eligibility

Eligibility for internships generally falls into three buckets: academic standing, work authorization, and field-specific prerequisites.

• Enrollment status: most internships require you to be enrolled in a degree program, while some accept recent graduates within one to two years of finishing.
• Academic performance: many programs state a minimum GPA (often 3.0 out of 4.0), though for non-academic roles strong projects can compensate.
• Language: you need working proficiency in the internship language. For English-taught roles, proof is usually your university's medium of instruction or a test like IELTS, TOEFL, or Duolingo.
• Work authorization: required for any paid position. Unpaid and remote volunteer roles have fewer legal restrictions.
• Location constraints: some roles require you to be in a specific city or time zone, while remote internships are open to applicants anywhere.

If you are missing one requirement, it does not always disqualify you. Many employers treat criteria as preferences, and it is usually worth applying if you meet the core ones and can explain the gaps.

What employers actually look for

Hiring managers rarely expect interns to know the job. They hire for potential, then train the rest. In practice, employers screen for these four things:

1. Fit and interest: a genuine, specific reason for wanting this role at this organization.
2. Communication: clear writing in the application and confident, structured answers in the interview.
3. Reliability: evidence that you meet deadlines, follow through, and handle feedback professionally.
4. Base competence: enough command of the basics that training can focus on the specifics of the role.

For interview preparation, our internship interview guide lists the most common questions and how to answer them.

Requirements by internship type

Different kinds of internships add different expectations on top of the basics.

Whatever the type, the same preparation rule applies: give yourself four to six weeks to assemble documents, tailor each application, and practice for interviews.

What to prepare before you apply

Preparation is what separates strong applications from weak ones. Work through this sequence:

1. Research the employer. Read their website, recent news, and the exact internship description. Note the tools and terminology they use.
2. Refresh your documents. Update your CV with your latest coursework and activities, and tailor the summary line to the field.
3. Secure your references. Ask your two or three referees now, not the week before the deadline.
4. Write a tailored cover letter for each application rather than reusing one generic letter.
5. Prepare your portfolio or practice environment if the role needs one.
6. Confirm logistics. Check start dates, location or time-zone fit, and any visa or work-authorization implications.
7. Plan your availability. A typical internship runs 8-12 weeks full-time or 10-20 hours per week part-time.

Common mistakes to avoid

• Sending the same application everywhere. A generic CV and cover letter signal low interest. Tailor each one.
• Overstating skills. Claims you cannot back up in an interview will end the process quickly.
• Ignoring instructions. If the posting asks for a specific file name or format, follow it exactly.
• Missing small details. Typos, wrong dates, and broken portfolio links are among the most common reasons applications are rejected.
• Applying at the last minute. References and transcripts take time; a rushed submission shows in the quality.
• Not following up. A polite follow-up email one to two weeks after applying is normal and can keep you on the recruiter's radar.
