Some of the teaching staff have received national recognition for their work. One example is Former Head Teacher Science, Carolyn Hayden. The school is notable for its traditions such as Green Day, which is held annually.
Lambton High School offers a gifted and talented students program to several years with Year 7 students completing a 'Master-Minds' course, Year 8 students completing an Authentic Learning Assessment, select Year 9 students being part of a semester GATS Class completing projects of their choice, and Year 10 students participating in an "Authentic Job Interview" at school. Talented students are asked whether they would like to participate in the accelerated Higher School Certificate and university courses in a wide variety of fields. Some year 10 students are also given the opportunity to participate in a 10 unit University excelleration programme where they can complete 10 units of a field of their choice. As part of Lambton High School's GATS program, students are encouraged to excel in all areas of their education: academic, sporting, cultural and leadership activities. In 2009, Carmel Tebbutt, the NSW Minister for Education presented 40 students from all NSW public schools with a Minister's Award for Excellence. Three Lambton High School students were fortunate to receive this award, Annabel Fleming, Caitlyn Read and Leah Serafim. This was the greatest number of awards received by any one school within the state.
At the 2009 HSC, Lambton High School ranked 143rd in New South Wales, up from 150th in 2008. In 2008, it increased its student "All rounders" from 33 to 47. However, in 2014, Lambton High's HSC ranking fell to 388th in the state from 198th in 2013, which was the largest decline of any school in the Newcastle, Lake Macquarie, Upper Hunter or Central Coast Region.
Student leadership
Lambton High School promotes student leadership through groups such as the "Prefect Body" and the "Student Representative Council". The Prefect Body is made of sixteen Year 12 students who are elected by peers and staff for a period of twelve months. This body is led in turn by the school captains, the vice-captains and the senior prefects. Carolyn Hayden is responsible for student leadership. The Student Representative Council, is made up of two students from each year group and the senior prefects. This group is elected in early February each year and in turn elects its own leaders. The school principal is responsible for the SRC. Other leadership opportunities are available through various sporting teams and environmental committees.
