Tilingatar Higher Secondary was informally formed as Panchakanya Primary School in 2017 BS (1960 AD) with strong initiation of late Lal Bahadur Rana (Magar) and late Kedar Bahadur Basnet, in Dhapasi VDC-7. Two years later in 2019 BS (1962 AD) it was formally founder under the registration of HMG Ministery of Education.
The school had to face many ups and downs and as a result the classes 4 & 5 were collapsed in 2030 though it was registered till class 5. The situation of the school went worse day by day but Shivasharan K.C. a dweller of Dhapasi-1, provided the school with tinned roof. A new ray of hope inspired gradually and the school was upgraded to classes 4 and 5 in 2040 and 2041 and 6 and 7 in 2042 and 2043 with private source. But there were many hindrances due to the lack of building and teachers, so it remained in class 7 till 2044. In 2045 the school was upgraded to class 8, as a proposed secondary school with strong initiation of the then headmaster Hari Lal Shrestha, teaching staff and 21 students of class 8, likewise class 9 and 10 were started gradually in 2046 and 2047. The school sent its students for SLC who secured satisfactory result in 2048 for the first time in secondary level on 2052.09.13 as per the decision of the Government. The permanency of the school has made everyone run more enthusiastic and optimistic on the further of the school. In 2059, the school conducted 10+2 in Management and in 2060, graded to multiple faculties.
