This is the latest in a series of case studies highlighting best practices High Schools That Work (HSTW) network schools and districts are implementing to prepare students better for further studies and careers. Fort Mill High School is in Fort Mill, South Carolina, an outlying suburb of Charlotte, North Carolina. Fort Mill links high quality career-technical instruction to rigorous academics and effective advisement. The school has also made significant progress in putting into practice HSTW's key priorities for continuous school improvement. It has established "The Power of I" redo/reteach and relearn policy, an extra help center, a mastery algebra program, and enriching career-technical studies linked to rigorous academics. These improvements have helped Fort Mill earn an on-time graduation rate of more than 90 percent. Two appendices are included: (1) High Schools That Work (HSTW) Key Practices; and (2) HSTW Goals for Continuous Improvement.
