Ann Arbor Public Schools have reopened! Schools began the process on March 25 with the last group returning on May 3.
AAPS began a phased return to in-person hybrid learning on March 25 and completed the return on May 3. Return is by family choice with the option to remain fully virtual. Returning students attend 2 days a week based on last name and attend virtually the remaining days. If you wish to return to hybrid learning, you must contact the school to register.
Grades PreK, Y5, K, and self-contained classrooms returned for 1 day (half Thursday and half Friday) before spring break. The week of April 5, grades 1-3 returned, and April 12 3rd grade returned. Due to rising case numbers in Michigan, AAPS took a break before returning grades 4-12. The week of April 26th some students returned for various testing. Then, the week of May 3, hybrid learning began for grades 4-12.
Middle and high school students only return for half-days due to the distancing needs around offering lunch. At high school, the return this week has them learning a completely new daily schedule as each of their 3 daily classes meet for 65 minutes in the morning followed by transport home/lunch which is then followed by advisory (optional on Tuesday/Thursday) and 30 more minutes of each of their 3 daily classes (followed by the unchanged optional 7th period for those choosing that.
While cases were still high at the time of reopening, several factors have allowed the reopening process to continue – after a pause for the older grades.
Teachers and school staff have all had the opportunity to be fully vaccinated. Not only is this important for teachers health, it is also a major factor in ensuring adequate staffing. Fully vaccinated individuals do not have to quarantine after an exposure.
The district is now able to offer weekly rapid testing to all interested families. Currently, these clinics are scheduled on Sundays at Huron High School for the remainder of the school year.
Additionally, at the high school level many students are now eligible to receive the vaccine (hopefully extending to ages 12-15 soon). My 9th grader is staying home, but if she was old enough to be vaccinated, she may have returned.
Class of 2021 Graduation
The Class of 2021 will have graduation in person outdoors at the high schools. The comprehensive high schools will split graduation in half to allow for family attendance and remaining in the spectator guidelines. They are hoping for 4 tickets per graduate. Ceremonies will be broadcast live and replyaed on CTN.
- June 1 – Pathways at Huron High School – 6:30p
- June 2 – Huron at Huron High School at 5 & 7:30p
- June 3 – Pioneer at Pioneer High School at 5 & 7:30p
- June 4 – Community at Pioneer High School at 6:30p
- June 7 – Skyline at Skyline High School at 5 & 7:30p
Graduations will be held rain or shine with an alternate plan for severe weather
The 2021-2022 school year will begin on Monday, August 30. AAPS planning for a full, 5 day a week in person opening. Based on advice from experts, it is believed that conditions will allow for this by fall. With a vaccine approved and readily available for ages 16+ and approval for ages 12-15 imminent, reopening secondary schools should be safer than today. Hopefully a vaccine will be available to students under 12 before school starts in the fall.
AAPS is encouraging everyone to get a vaccine when they are eligible.
A full virtual option will be an option in 2021-2022, but they are not planning on hybrid.
I have heard that Skyline High School will be returning to trimesters in 2021-2022.
With the revised CDC guidelines released on February 12 and the availability of vaccines, the district has moved away from their past metrics. Instead they are using the CDC guidelines of cases in a 7 day period per 100K people and percentage of positive tests.
As of February 24, Washtenaw County is considered high risk of transmission due to case levels despite low testing levels. At this level, elementary schools can be in hybrid or reduced capacity. Middle and High Schools should remain virtual with some exceptions.
I am leaving the original comments below with the last sentence in bold which highlights the prediction on October 28 that metrics could be increased .with better testing (availability of rapid testing in schools) and vaccine (now available for teachers and staff)
Since the metrics were first introduced at a planning meeting on September 11 and the board meeting on September 16, they were finalized. The original draft metrics set a strict limit. The adopted metrics include a higher level that they will consider re-opening. This allows for more flexibility to hit only some of the goals if others are close. At the October 28 Board Meeting, it was discussed that these numbers may adjust higher as we move from a novel pandemic to an endemic stage. With better testing (accuracy and speed of return), a vaccine, and increased contact tracing, exponential growth can be better managed.
Where we Have Been
Original Key Metrics
The district is focusing primarily on 4 key quantifiable metrics. Each will be looked at predominately on a county basis, but will also look at the greater region and state totals:
- Trend of New Daily Cases – Looking at this week to week and total number – They are looking for a decrease or a flat trend at a low number
- New Cases per Million* – Low risk is <7 cases, but Washtenaw County has never been at this level since the first reported cases and it is probably unattainable. Medium Risk is 7-20 cases and the goal for resuming class.
- Aim: <20 cases per million
- Consider: 20-40 cases per million
- New Cases per 100,000* – Medium risk is 1-10 daily new cases.
- Aim: <5 cases/100K to be more consistent with the cases per million
- Consider: 6-9 cases/100K
- Positivity Rate of Diagnostic Tests – Harvard Global Health recommends <3% which is the same as MI Safe Start. As a note, NY is using <1% as their metric.
In addition, the district is looking more qualitatively at the reported cases in the county among students in PreK-12 and individuals age 0-18. They are also starting to look at hospitalizations as recommended in public commentary. They did point out that hospitalizations tend to lag other indicators.
Note: New Cases per Million and New Cases per 100,000 are reported by different groups and are not off by just a factor of 10. The Cases per Million are reported by MI Safe Start and uses onset of symptoms to assign dates. The Cases per 100K are reported by the Harvard Global Health Initiative and are based on test date. One uses just lab confirmed cases and the other also includes probable cases. It was not clear which metric uses which term.
November 11 Report
At the November 11 board meeting, the report is that COVID numbers continue to get worse throughout Washtenaw County and Michigan. I did not pull the charts, but cases are on the rise, percentage of positive tests are on the rise, hospitalizations are up, test turn around time is up, contact tracing is reaching capacity, etc.
The district shares the following graph on their COVID Metrics Dashboard.
As recently as October 9 we were approaching the top of the consider range. The New Cases per 100K were just barely under the limit however the new cases per million were still 20% over the limit.
September 16 Data
The September 16 data and chart were released before the consider range was included. However, looking at the data now we were at the top of the consider range. Unfortunately, since that time, cases have continued to grow.
The district’s plan was originally to evaluate the data at the end of each month and make a decision with the board of whether it was safe to return to school. In discussion, they have moved towards setting a policy that the board will approve and evaluate the data on a rolling basis. Once the metrics are met, they will monitor the data for 14 days to ensure that conditions remain the same or improve. When the metrics are satisfied, the board will notify the board and parents. During this two week time, they will begin the ramp up to return to school. This includes reconfirming parent’s choice on return to buildings, creating cohorts, and other final preparations for in-person learning. At the end of the two weeks, they will set a return to school date.
Return will be phased in 3 stages starting with young elementary (Young 5-2nd) and those for whom virtual learning presents a significant challenge (special education with high impact, English Language Learners, and those with additional needs). Stage 2 will be grades 3-5 and stage 3 will be secondary students.
Return to School will be in the hybrid model with students returning 2 days a week or remaining home. If space allows some high risk students may return 4 days a week. When students are at home, they will be connected to the in person class and teacher via Zoom meetings.
A major part of returning to school is ensuring the buildings are prepared. This includes attention to air handling, spacing, layout modifications, touch surfaces, signage, and more. Building preparations were covered in the Board Study Session on October 21.
Since school closed in March AAPS has been making some of these needed changes. Changes were prioritized to facilities for high school sports which have been in use since summer, then proceeding through buildings by grade level according to the phased reopening plan.
The good news is that some of these permanent changes will help with all disease transmission even when COVID-19 is no longer a major threat.
COVID-19 is largely an airborne disease. The majority of the buildings in AAPS are old with old HVAC systems. The district has been working with a contractor to help adjust these systems. With the extended closure since March they have had more time than a typical summer to do more extensive maintenance. They are working to increase filtration. They showed a study of how increasing the MERV value of a filter can reduce spread of the flu from 32% to around 12%. The maximum MERV level is dependent on the air handling systems and how much air they can pull through a denser filter.
They are also increasing the percentage of outside air to help reduce the quantity of the virus. Using increased outside air is a trade-off for cleaner air vs increased energy consumption in winter months and even the ability to maintain temperature in rooms..
The goal is to turnover the air in a room 4-5 times an hour. This is difficult to achieve in some classrooms based on layouts and configuration. The district is investigating adding room air purifiers to help with air turnover particularly in the difficult to ventilate classrooms. As of October 28, they are prototyping a few units and investigating supply chain procurement issues before proposing a purchase to the board.
Water quality includes several different issues – bacteria growth in the water plus water fountains and bathrooms being transmission sources.
Extended building closures can cause growth of e coli and legionella bacteria. Throughout the closures, AAPS has been diligent about flushing systems to prevent the growth of bacteria. They have also completed their semi-annual filter replacement program.
They have removed the bubblers from water fountains and are adding touchless bottle filling stations.
Bathrooms are being converted to touchless operation. Touchless sinks and toilets. They are also removing air blowers and switching to paper towels. The air blowers can blow germs around and are no longer recommended in restrooms. This process may take more than a year to reach all bathrooms and buildings.
The district is working with a consultant to design classroom layouts. Unfortunately, we don’t have standard classrooms in the district. They vary in size and shape and air handling which affect the optimal layout for each room.
Signage, Flow, & Barriers
AAPS is working to redesign building flow. They are converting hallways, doors, and stairs to one way flow in many cases – especially when you cannot keep 6′ of spacing between people moving in opposite directions. They have new plexiglass barriers for offices, cafeteria, and other locations. They are installing social distance reminders in hallways, new signage for new traffic flow, and hand washing reminders.
Supplies for Returning to the Building
When in person learning resumes, the district will need to have adequate supplies.
PPE & Related Supplies
The Board has already purchased PPE that is estimated to last about 2 months at full capacity. They are working to make sure they have a supply chain that they will be able to restock when needed. (Personal note, I know my husband has had trouble purchasing gloves for his laboratory).
They are also investigating what is required for disposal of items. When working with probable or known cases, PPE needs to be disposed of as medical waste. They are working to extend their sharps disposal to cover that.
School supplies were purchased and distributed for families to use at home already. A second purchase is being made to restock classrooms as they do every year. The district does not expect the supplies sent home to return.
On October 14, a first briefing was presented for purchase of road salt and for a snow removal contract. These funds were approved at the October 28 board meeting. These purchase are needed to make the buildings safe when students return. Although some winter maintenance will also be done if buildings are closed.
As part of the MDHHS orders, student athletes are tested weekly. Masks are required for contact sports (previously for all sports). Middle school athletics are not happening.
