Rainbow Home -  It was started as a school within a school in 1991 to meet the needs of the numerous street children living around the school. It was to give them a head start through which they could be prepared for eventual admission into a regular school (Corporation School, Hindi / Bengali School and in Loreto Day School, Bowbazar). Today there are about 210 children. In 2002 a night shelter was started and now over 150 girls stay in the school premises. Out of 150 girls, some still attend classes in Rainbow Home while others attend the main stream Regular School at Loreto Day School, Bowbazar, Union Chapel, Corporation School, St. George’s School and Loreto Sealdah. The mainstream teachers and students participate in the Teaching Learning Programme of Rainbow Home alongside 3 Regular Rainbow Home Teachers.
