One of the biggest challenges for me this year was the (extremely!) high mobility rate at my school. A couple people asked me for specific numbers and at the time I hadn't sat down and counted. Having just finished assembling our third grade yearbook, I had the chance to actually see how many students have come and gone from my class. Here's what a 39.5% mobility rate looks like:
Roster prior to the start of school: 30
First day attendance: 24 from roster
4 students transferred in within the first two weeks of school.
2 students left by the end of September.
1 more left in October.
2 students arrived in December.
3 students arrived in January.
1 student ARRIVED AND LEFT in April.
1 student LEFT THEN REENROLLED in April.
1 additional student left in April.
1 student left in May.
2 students left in June.
4 students neither started nor ended the year with us. In general, the students who transferred in mid-year had much poorer attendance than the rest of the class. They were sometimes absent whole weeks, or even multiple weeks at a time.
Total number of students transferring in (after the first two weeks of school, and not counting the same student transferring in twice): 6
Total number of students transferring out: 10
Next year I'm at a charter school. While I feel strongly about public education, as a teacher, I have to say I am looking forward to some stability in my classroom again. (My first year at Hope I had just one student transfer out: no other mobility).
Update: according to this page regarding how to calculate mobility rate, the actual mobility rate in my classroom was 47% (higher if you count the 4 students transferring in the first two weeks, which I haven't.)
