His period saw parents changing their attitude towards the welfare of their children, leading to a vibrant Parent Teacher Association which led subsequent Development in the school. He also saw the landscaping of the compound. In April 1999 upon the retirement of Mr. Ben Koteye, the mantle fell on Mrs. Sylvia Asempa, the first female to head the school. She continued the good works that her predecessors had set in motion. It was during her time that Accra Ring Road central with support from the Rotary foundation of Rotary International constructed a multi-purpose playing court on the reclaimed waterlogged triangle of the school. She was also the first bilingual Headteacher of Accra High School. She spoke fluent French hence the further development of the French as a foreign Language in the school. The P.T.A. Converted the basement of the existing school flat into two, two bedroom unit for staff occupation as well as the establishment of a 150 million computer laboratory for the school. It is worthy of note that some old students also contributed some of the facilities used in the computer lab. Mrs. Asempa was later transferred to Aburi Girls Secondary School to continue her excellent work. Under the administration, the bust of the founder was erected on the fore court of the administration block. In March 2002, Accra High School was blessed with yet another dynamic headmaster in the person of Mr. E.A. Kissiedu. Although he has been head for a brief period, he has re-equipped the chemistry and the physics labs, paved the alley in front of the classroom complex, upgraded office equipment sourced new computers for the internet security and constructed of kerbs along the road from the gate to the quadrangle to prevent the perennial erosion. His interest in the promotion of sports has boosted the moral of sports in Boys and Girls in the school. He handed over to Mr. Isaac Ohimeng Gyebi who served from 2006 to 2011. The school is currently headed by Mrs Betty Aduhene-Chinbuah who took over in 2011. Under her leadership, the school is pursuing a redevelopment agenda, with the active support of the alumni (AHISCOSA), to offer the school a facelift and ensure that AHISCO regains its past glory. Presently, the school runs five programmes, namely: general arts, general science, technical, business, visual art and home economics. The school also houses a science resource centre, French centre bureau de co-ordination nationale des cref and a completed office complex for the Ghana Education Service Council.
