The school was named after a prominent local lawyer, Isaac Ernest Weldon,[2] who left a generous bequest of money to the Victoria County Board of Education, with the stipulation that the interest generated annually would be divided amongst graduating students in the County advancing to post-secondary education.

The school's proximity to Kawartha Lakes City Road 36 caused council to request more frequent monitoring of speed limits by municipal police.

[4] I.E. Weldon Secondary School offers diversified programs focusing on academics, the arts, co-operative education, personal development and technical studies to meet the individual needs of students.

The school also offers a Specialist High Skills Major in construction, as well as a dual credit program with Fleming College in Peterborough.

Students and staff at Weldon contribute to Plan International Canada, which supports children in developing countries around the world.
