Carol Kirk told the education committee on Tuesday that the general trend for the Borders as a whole was an upward one, in relation to the number of qualifications achieved by pupils.
However, she added: “It has been an extremely fraught year looking at a whole new set of qualifications coming in.”
Ms Kirk said that the number of pupils achieving three or more and five or more qualifications at Higher level increased, with a fall in attainment only recorded in the new National 5 qualifications, which replaced Standard Grades and are intended to be more difficult.
“This shows that across the board we are broadly progressing,” Ms Kirk said.
A more detailed report will be provided to the committee in November, once detailed figures are available for “comparator” school groups, which are based around socio-economic factors and enable a comparison to be made between similar schools.
However, Councillor Catriona Bhatia emphasised that it was important that even if a secondary school is performing well within its comparator group, efforts are maintained to close the “attainment gap” in the area.
Joe Walsh, the Roman Catholic representative on the committee, also called for best practices to be shared between schools, and urged the council to look within the authority for examples of this, rather than necessarily outwith the area.
Ms Kirk added that it was important to look at pupils’ wider achievements and learning in school, not just exam results.
