The Tianjin International School was founded in 1985 to provide an American educational program for the children of LDi (formerly MTI) employees. Classes began in the fall of 1986 in temporary classrooms at the Tianjin Grand Hotel Conference Center. The school initially had 30 students, 6 full-time teachers, and several part-time teachers.In May of 1987, the school moved to the eighth floor of the Intertech Building. In 1991, the school expanded to include children of expatriates living and working in Tianjin or its surrounding environs. The school quickly outgrew its classroom space at the ITC Building and moved to the Xing Guo Junior High School building in 1993. During its seven years at Xing Guo, the school continued to grow and expand its program offerings.In the summer of 2000, TIS moved into the Sun hope Building in the Huayuan Technology Zone, which provided much needed room for expansions of its programs. After more than a decade there, the school moved back to the Hexi District and opened its doors at the current campus on January 30, 2012. In what was a miraculous provision, the school campus more than doubled in size and added many facilities that increased the richness of the student experience.天津国际学校成立于1985年，为本地设计院（原MTI）员工的子女提供美国教育项目。1986年秋天，天津大酒店会议中心的临时教室开始上课。学校最初有30名学生，6名专职教师和几名兼职教师。1987年5月，学校搬到了Intertech大楼的8楼。1991年，学校扩大到包括在天津或周边地区生活和工作的外籍人士的子女。学校很快就超出了国贸大楼的教室空间，并于1993年迁至兴国初中大楼。在兴国的七年里，学校继续发展壮大，扩大了课程设置。2000年夏天，天合光能搬进了位于华远科技区的太阳希望大厦，为其项目的扩展提供了急需的空间。经过十多年的努力，学校在2012年1月30日回到了河西区，并在校园里开门。这是一个奇迹，学校的校园面积增加了一倍多，并增加了许多设施，增加了丰富的学生体验。
