ISV Mission Statement

ISV's mission is to support sustainable development initiatives around the world through life-changing student volunteer and responsible adventure travel programs designed to positively change our world and to educate, inspire and result in more active global citizens.

What is ISV? To know anything about ISV, look beyond the logo and brochure, and look at the people who breathe life into the organisation.

ISV is a family, joined together by our commitment and passion for contributing to a better planet and helping disadvantaged people.

We pride ourselves on our dedication, values and ethical approach to all that we do, but also on our collective professional and academic experiences in volunteerism, sustainability, outdoor leadership and adventure, and student-care.

We are women and men from multiple countries around the world who share our common vision. We are biologists, social workers, intrepid travellers, young and young at heart, students and also people with families of our own, so we can relate to what it means to send our loved ones overseas.

Longevity is powerful. Many staff have served for ISV for 10 or more years, and a big part of our student care office teams are made up of ISV alumni, who understand the needs of volunteers well, having personally experienced the ISV program themselves. Our program directors have also served as project and tour leaders, so they can directly relate and are equipped to the challenges we face on a daily basis in volunteerism and travel.

True to our stated values, we believe in building capacity locally, and our host country offices are run by talented full time local employees and citizens who have the deepest commitment to developing and facilitating the most meaningful and effective programs possible for their own countries.

ISV is a family, and there are no better people to guide you on your volunteer and travel experience anywhere.
