What Are the Best Summer Language Programs for High School Students?

The best summer language programs for high school students are the ones that let you actually live the language—speaking it every day, exploring new cultures, and sometimes even staying with host families for a fully immersive experience.

These programs help you build real fluency, strengthen your communication skills, and become more resilient and adaptable as you navigate life in a new environment. Along the way, you’ll discover global cultures through food, history, art, and travel, gaining the kind of international experience that stands out on college applications.

Below, we break down the top 10 language immersion programs for summer 2025, starting with a quick overview and then diving into each one.

Let’s discuss each program one by one.

1. NSLI-Y (National Security Language Initiative for Youth)

• Dates: mid-June to mid-August: Summer Abroad (6–7 weeks); Academic Year Abroad (8–10 months); September to November: Virtual NSLI-Y (10 weeks)
• Location: Abroad in host countries where the target language is spoken; online Virtual NSLI-Y
• Cost: Free; fully funded scholarship

NSLI-Y is a U.S. Department of State–funded program that sends American high school students abroad (or online) to learn languages like Arabic, Chinese (Mandarin), Korean, and Russian.

You don’t need any language experience at all. NSLI-Y is open to U.S. citizens ages 15–18 in grades 9–12 with a GPA of 2.5 or above. The application also requires essays, transcripts, and a recommendation letter.

If you choose the summer abroad program, you’ll spend 6–7 weeks taking intensive language classes, exploring your host city, and living with a host family—all of which help you level up your language skills super fast. Academic year students go even deeper, attending local schools and becoming part of the community. If you’d prefer to start from home, Virtual NSLI-Y meets twice a week and gives you a fun, low-pressure introduction to the language and culture.

NSLI-Y is a life-changing experience because it’s 100% free. It opens doors for students from all backgrounds to build global confidence, make friends from around the world, and return home with a new perspective (and probably a few favorite foods, too).

2. CIEE High School Summer Abroad

• Dates: June–August (3–4 week programs; exact dates vary by destination)
• Location: 40+ global locations including Spain, France, Italy, Japan, South Korea, Germany, Morocco, Costa Rica, Portugal, Argentina & more

CIEE’s High School Summer Abroad programs are some of the most popular summer language programs for high school students.

CIEE offers programs in over 40 countries, from the Mediterranean coast to East Asia. Each program lasts 3–4 weeks and is fully in-person, combining structured language instruction with hands-on activities and real-world practice.

Students can study Spanish, French, German, Italian, Mandarin, Korean, Arabic, or Japanese while living with local host families or staying in supervised residences. CIEE’s Language & Culture tracks also include the Avant STAMP 4S test before and after the program to measure language growth.

A major highlight is the opportunity to earn 4 college credits from Tulane University by opting into the credit-bearing track. Programs are open to rising 9th–12th graders, and CIEE offers one of the most generous aid packages in the country through the Global Navigator Scholarships, with over $7 million awarded annually.

LITA is a Spanish immersion experience that’s designed for high school students who have taken at least three years of Spanish. LITA drops you right into rural Spain, where you’ll live with a host family, explore small towns, and use Spanish every single day—from cooking with your host mom to joining festivals you won’t find in a guidebook.

Each program begins with a group orientation before you head into a 12–21-day homestay where you become part of a Spanish family. During your stay, you’ll choose either an internship (like helping at a bakery, museum, café, or summer camp) or a cultural project, giving you the chance to use Spanish in meaningful, real-world situations.

Outside the homestay, you’ll enjoy hikes, cooking workshops, day trips to cities like Burgos or Salamanca, and a closing adventure in regions like Sevilla or the Basque country. LITA also prioritizes safety and community—you’ll travel in a small group with two experienced leaders and receive a Spanish SIM card to stay connected.

Eligibility includes a short, no-pressure conversation with LITA staff to make sure you’re ready for full immersion. Limited financial aid is available, with applications due January 31.

Programs run 1–8 weeks, all fully in-person, and every destination is built around immersion. Students also follow the AFS Student Learning Journey, a guided curriculum that helps you reflect on your growth, and some programs even offer ACTFL AAPPL language proficiency testing so you can document your gains.

Instead of a traditional classroom, CLV creates whole “language villages” in Minnesota where teens live, eat, play, and learn entirely in their target language.

The Youth Overnight Camps program structure combines daily language classes, cultural workshops, team activities, and fully immersive role-play scenarios. Villagers also participate in cultural meals, music, dance, art, and international simulations that mimic real-life situations. Every village is staffed by fluent speakers and international counselors who help students build confidence and real communication skills through constant interaction.

This summer program in Düsseldorf is designed for students aged 14–18 who want to boost their German skills and explore one of Germany’s most livable cities.
