The Student Transition project (STP) has collected eleven years of grade 12 and post-secondary enrollment data, since it's inception in 2003. This information is used to track student transitions from grade 12 graduation into post-secondary education, student mobility between post-secondary institutions and post-secondary credential completions. Each year, the STP provides a Student Transitions Matrix showing the number and proportion of students who first enroll in the British Columbia (B.C.) public post-secondary education system in each academic year after grade 12 graduation (see Figure 1). This matrix also provides the cumulative proportion of each graduation cohort that enrolled in a B.C. public post-secondary institution within one, two, three or as many as ten years. While the majority of students (50% to 53%) who enroll in the B.C. public post-secondary education system do so immediately after grade 12 graduation, a further 10% to 12% enroll after one year, 5% wait two years and then in each subsequent year, a progressively smaller proportion of students (3% or fewer) enroll. The STP continues to measure and report these rates every year for planning purposes
