Policy Group Works Reviewed: Organizing Schools to Improve Student Achievement: Start Times, Grade Configurations, and Teacher Assignments – The Hamilton Project / Brookings Institute Impact of School Start Time on Student Learning – Hanover Research School Start Time Change: An In-Depth Examination of School Districts in the United States – Children’s National Medical Center’s Blueprint for Change Team (CNMC) Policy Groups 7
8
Academic Improved grades and academic success (Hamilton, Hanover, CNMC) Reanalysis of data from Minneapolis and surrounding districts found neither attendance nor ACT scores changed relative to districts that started earlier (Hamilton) Attendance Beneficial to truancy rates (Hanover) Better attendance rates in some districts (Hanover, CNMC) Policy Groups - Findings 8
9
Behavior: Health Fewer automobile accidents (Hanover) Improvements in student mood and alertness (Hanover) Less engagement in high risk behavior (Hanover) Budget Varies from district to district; sometimes no cost, save money or costs could increase (Hamilton) All schools surveyed in CNMC study noted cost savings, “likely attributable to adaptation of an increased number of busing tiers.” (i.e. only two (2) of the eight (8) districts responding had tiered busing prior to change) (CNMC) Policy Groups - Findings 9
10
National: 14 Case Studies Districts / Schools 10
11
Districts / Schools - Findings 11 Unfortunately, many schools neither defined success nor measured results after implementation Student Academics, Health, Athletics, Childcare and Transportation were common concerns throughout the study process (if district did a study) Budget data not commonly documented Frequently, the same sleep research and studies cited by districts when studying the change
12
Districts / Schools - Findings 12 Varied Implementation Models: – Start Time Slides – Straight Flip – Modified Flips – Started Tiered Busing in Conjunction with Change CNMC – six of eight districts that responded moved to tiered busing when changing school start times – Piloted / Phases Implementation Ex. Minneapolis – changed times in seven (7) comprehensive schools and now reexamining issue for other schools in 2015
13
Districts / Schools - Findings 13 Varied Costs (when documented): – Ex. Montgomery County cost neutral Original Recommendation would have moved High School 50 minutes later and cost an estimated $21.6 million Board asked for modified recommendation – new plan extends Elementary day by 10 minutes (for lunch/recess) and High School starts 20 minutes later (to 7:45 am) – Ex. Fairfax County $4.9 million 27 additional buses; High School moves from 7:20 am to 8/8:10 am – Ex. Columbia Public Schools (Missouri) saved $1.3 million by moving from two tier to three tier busing High School moved from 7:45/7:50 am to 8:55/9:15 am start
14
Regional: 5 Case Studies Districts / Schools 14
15
Districts / Schools - Findings 15 Of the five regional districts examined, two studied the issue and three are currently in progress; same concerns as Seattle Mercer Island previously moved start times for High School from 7:20 to 8:00 am in 2003; partnering with Bellevue District to study later start times with a Committee Recommendation by May/June 2015 Northshore studied later times in 2012 and chose not to implement; School Board passed Resolution No. 714 directing High School start times be no earlier than 8 am in conjunction with opening of North Creek High School (2017-18 year) Issaquah School District studied in 2003 to 2005; Committee recommended a slide of 15 min; full recommendation not taken up by the Board; Too expensive to Implement (HS 7:25 am)

Districts / Schools - Findings * Source: Academic Data Warehouse 17 Academic: Grade ‘E’ in Period 1 – First Period, Rate of E Grades (equivalent of a failing grade) – Of the five High Schools examined over three semesters, the highest percentage of failing grades in Period 1 is at Nathan Hale Note: current request in for demographic breakdown of data
18
Districts / Schools - Findings * Source: Academic Data Warehouse 18 Academic: On Track/Off Track* – Highest ‘On Track’ to Graduate % – Cleveland HS (98.44%) – Nathan Hale: 97.05%, Chief Sealth: 95.64% * ‘On Track’ based on the student’s current grade, projected graduation year, and the number of credits accumulated in the current academic year

Reminder: Confounding Variables Correlation, not causality Data not weighted Districts / Schools - Findings 25
26
Academic (Green): Many of the same statements as Policy papers However, begin to see researchers suffered many of the same problems with data quality issues and correlations Researchers added many caveats to papers: – Example: “In reality, grades are often a rather subjective measure due to local factors such as grade inflation, curricular changes, teacher and administrator turnover, and changes in assessing student work.” (Wahlstrom, 2002) – Example: “Although studies find a correlation between sleep and grades, they cannot establish a causal relationship. Additionally, much of the existing literature relies on surveys and self-reports, which are both retrospective and subjective. Differences in academic achievement measures across studies make cross-study comparisons difficult and many suffer from small sample size.” (Carrell, et al, 2011) Applied Research - Findings 26
27
Attendance (Blue): Many of the same statements as Policy papers Showed strong support for increased attendance levels – Example: (Wahlstrom, 2014) Applied Research - Findings 27
28
Attendance: Longitudinal Study examined attendance by Race/Ethnicity (Wahlstrom, 2002) Applied Research - Findings 28
29
Behavior: Health (Orange) Many of the same statements as Policy papers Studies examined a number of health factors Findings: – Drop in car crashes for 16-18 year olds in Minnesota and Wyoming – Decrease in depression rates – Improvements in adolescent alertness, mood and health – Connection between getting less than 8 hours of sleep a night and obesity – Associations between certain types of sports injuries in youth Applied Research - Findings 29
30
Caveats: Often seeing correlation and not causality Difficult to find a representative cultural and socioeconomic sample for research Results often based on adolescents’ retrospective, self- reported information and “suffer limitations” “Caution should be taken in generalizing the findings” (Wolfson, A., & Carskadon, M., 1998) When studies “cross-sectional, no conclusions about long- term development and ramifications of inadequate sleep can be drawn” (Wolfson, A., & Carskadon, M., 1998) Applied Research - Findings 30

Organizing Schools to Improve Student Achievement: Start Times, Grade Configurations, and Teacher Assignments – The Hamilton Project / Brookings Institute Academic: “Recent studies provide compelling evidence that later school starting times could substantially improve the academic achievement of adolescents.” - Commented on “countervailing evidence” of a reanalysis of data from Minneapolis and surrounding districts; found neither attendance nor ACT scores changed relative to districts that started earlier; “… it is likely that ACT does not fully capture changes in student learning.” Budget: Varies from district to district; sometimes no cost, save money or costs could increase - Based on research, future earnings of students could potentially increase Policy Groups - Findings 39
40
Impact of School Start Time on Student Learning – Hanover Research Academic: “Based on the findings of this report, school districts could increase student safety and boost adolescent academic success by instituting later start times for middle and high school students.” “…elementary school students do not benefit from a later start time.” Attendance: “…even a modest shift in school start time benefits…truancy rate[s]…” Health: “…fewer automobile accidents and less engagement in high-risk behavior…” “…improvements in measures of student mood, alertness, and health in adolescent students.” “…better driving and subsequently fewer accidents.” Policy Groups - Findings 40
