Meridian Secondary School

Meridian Secondary School is a co-educational government secondary school in Pasir Ris, Singapore. It was formed by a merger between Coral Secondary School and Siglap Secondary School in 2017.

Coral Secondary School (1999–2016)
Coral Secondary School opened in January 1999 with six Secondary One classes: three Express classes, two Normal (Academic) classes, and one Normal (Technical) class. The initial staff comprised 17 teaching staff and eight support staff. The school began its lessons at Siglap Secondary School and moved to its new premises on 15 November 1999. It was officially opened on 19 May 2001 by Education Minister Teo Chee Hean.

The original name of the school in Chinese, Shanhu, is a literal translation of "coral". However, it had been changed to Yunhai, which can be interpreted and written in two versions: the original or the simplified form. The original version literally means cloud and sea. It is believed that corals grow well in the sea with a cloudy sky. The Chinese characters emphasises the importance of tradition and culture as well as the beauty of art and music. Hence, the school has adopted the original version of the interpretation of "coral".

Siglap Secondary School (1955–2016)
Siglap Secondary School was Singapore's first co-educational government secondary school. It was also one of the first schools in Singapore to offer Malay-medium secondary classes. The school was founded in 1955 and shifted from its original location of Cheviot Hill in Siglap to its current location of Pasir Ris in the eastern part of Singapore.

In 2000, the school moved from its old campus at Siglap to the new premises at Pasir Ris. The newer campus included upgraded facilities to hold more classes in a morning session and became a single-session school in the same year.

Merger as Meridian Secondary School
In December 2015, the Ministry of Education announced that due to a lack of demand, Siglap Secondary School would not receive a new cohort of Secondary 1 students in 2016. This was followed by an announcement in March 2016 that Siglap Secondary School would be merged with Coral Secondary School from January 2017 onwards. The school was renamed to Meridian Secondary School with the absorbing of Siglap Secondary School.

Motto
The motto of Meridian Secondary School is "Unite to Reach New Heights". This is a reflection of the spirit of the two predecessor schools, Siglap Secondary School (with the motto "Sagex et Audax" which meant Wisdom and Courage) and Coral Secondary School.

Uniform
The school uniform consists of a white shirt and dark blue pants for boys and a white blouse with dark blue culottes for girls.
