SHAPING TOMORROW | Yesterday St Leo's staff joined over 2000 of our Catholic Schools Broken Bay colleagues from all 45 diocesan schools across the North Shore, Central Coast and Northern Beaches for a Strategy Day at Barker College.![]()
It was an inspiring day, with Bishop Anthony officially launching the new vision for Catholic education following on from the achievements of the 5-year ‘Towards 2025’ strategy. The new strategy, ‘Shaping Tomorrow, Together in Faith’, commits CSBB to establishing new secondary school options and will also see the introduction of exciting new initiatives in early years education and career pathways. ![]()
