At this stage, only construction on the B-block had been completed, which created huge obstacles. Through the cacophonous din and clamour of construction, education continued. Assemblies were held on the lawn outside and later in the quadrangle. An academic policy was established which formed the corner stone of the school. A disciplinary code appropriate to the eighties and nineties was adopted and after much grappling and a myriad of meetings the characteristic jade school dresses, navy-blue blazers, grey pants, white shirts, ties and badge were designed and approved. The motto of Stellenberg, Vivat Scientia (Let Knowledge Live) was created. Op 23 November 1987 het die destydse Eerste Minister van die RSA die skool amptelik geopen. In 1989 is die skoollied onder leiding van mnr. Johan Pretorius geskryf en getoonset. Dit was ‘n aandoenlike en onvergeetlike oomblik toe 980 gr. 8 – 12-leerders in ‘n saal wat binne drie jaar te klein geword het vir die skool, die skoollied vir die eerste keer sing.

Through the accounting and mathematical ingenuity of Mr Sakkie van Niekerk and Mr Johan Pretorius respectively, the school’s innovative Honorary Colours system came to fruition. Messrs Neethling, van Niekerk and Pretorius, established the foundation on which Stellenberg High School continues to build. In 1996 tot 2020 is mnr. Theo Boonzaaier aangestel as skoolhoof. In 2021 word mev. Yolandé Havinga aangestel as die eerste vroue-skoolhoof. Tans is daar 1 480 leerders ingeskryf by Hoërskool Stellenberg met ‘n akademiese personeel van 76. In its thirty-seven years’ existence, Stellenberg High School has achieved remarkable accomplishments. This dual- medium institution continues to strengthen its budding traditions, fashioned by passionate, proud Stellies. Ons bring hulde aan talle onderwysers en oudleerders, sommige reeds oorlede, wie se stemme en steeds in ons gange weerklink.
