WZIS was founded by Moody Lee, who remains as President and owner of the school. He oversees the International School, Korean School, Kindergarten and Foreign Language Institute, which together make up the Zhongshi family of schools.

WZIS began as a foreign language institute serving Korean and Chinese students in the Weihai community. Due to the high quality of education provided, Moody was asked by the Korean community to start a Korean School and then later an international school. In 2006, the International School was officially recognized as an international school by the Ministry for Education and in August, 2006 it opened for the first time under the leadership and care of Gordon and Christine Harvey.

The student number grew quickly as WZIS was reputed to not only offer good education, but also excellent character training. As a result, in May, 2010 the school was relocated to a purpose built building on the outskirts of the city, where it currently remains. July, 2011 saw the first graduating class and four students were sent out to America, Korea, and Switzerland to pursue further study. That summer the first UK trip took place starting the trend for international field trips that has followed since.

In the 2011/12 school year the first WZIS soccer team competed in a regional competition in Qingdao. Thanks to the excellent sportsmanship of the students a strong relationship began to build between WZIS and the Qingdao schools, particularly ISQ (International School of Qingdao).

In July, 2012 Gordon and Christine Harvey retired as Principal and Vice Principal of WZIS and they were replaced by David Bedford and a new leadership team. The incredible contribution to the school will not be forgotten and we are blessed to be able to welcome them back during their annual visits.

In the 2012/13 school the curriculum continued to be improved and the extra curricular program began to change significantly. The school attended its first MUN competition, launched its first Science Fair, sent the grade 11 class to Borneo for a mission trip, and began the accreditation process. At the end of the year, three of the four graduates were awarded places at Yonsei University, one of the top universities in South Korea.

The 2013/14 year saw the introduction of the school house system, one of the features of the school that is best known in the community. The school started competing in regional table tennis competitions and construction began on the new school dormitory and Korean School building. A team of WZIS scientists were offered the chance to attend the International INTEL Science Fair in LA after winning multiple awards in the national event in Chengdu. The first internal MUN event was held and daily clubs were offered for the first time in the Primary School. YEASA was formed, improving our relationships and competitive opportunities with schools in the nearby city of Yantai. The school orchestra began in March and quickly grew. It now numbers over 90 students.

In 2014/2015 we competed in our first basketball and badminton competitions and our first regional debate contest. The first school play and orchestra performance took place in December and June respectively.The Primary School held its first Lollapalooza event and continued to offer a greater range of clubs in period 7. The dormitory was opened and for the first time full board students joined us from Korea and Qingdao. The first YEASA sports competition took place involving over 100 staff and students from the school.

The 2015/2016 will be the year best remembered as the year we received international accreditation from WASC (Western Association of Schools and Colleges). This great achievement was the culmination of three years of hard work, bringing WZIS in line with the stringent accreditation standards. We can now say confidently that we are a genuine international school, offering a strong program, and an excellent range of opportunities for our students.

The school has grown and developed quickly thanks to the hard work and dedication of the staff. We have been greatly blessed by the support we have received from our community and despite rapid changes, our close-knit family feel is stronger than ever. We continue to be sent fantastic teachers from around the world who bring their own unique gifts into the service of our community. Our parents are involved in many events and are always happy to offer support and advice. Above all, we stay focused on our mission, to send out servant leaders from China to the World.
