COVID-19 Update 11-10-2020



BCSS Update November 10, 2020


Dear BCSS families,


With all of the talk going on regarding the high positivity rate in Black Hawk County, we wanted to share with you some facts regarding the numbers in our system.


Since August 24 as a system we have had:

0.67% of students testing positive,  Currently, that number is 0%. 


If you are hearing about several kids being out of school, we ask that you remember that just because someone is absent, does not mean that they have Covid.


Our absences have been related to kids having to quarantine due to a positive exposure.  Most of those exposures have come from outside of school, within the household.  


We track our attendance daily, the highest percent absenteeism that we have had due to quarantine or isolation is 4.6%.


We continue to watch our data closely.  We follow the return to learn guide put out by the Iowa Department of Education that can be found here Return to Learn Guide.  Even with the substantial community transmission in Black Hawk County, our absenteeism rate remains well below the 10% mark.  


Our internal data strongly suggests the spread of COVID is happening outside the school setting. Based on this analysis, there is no doubt our mitigation measures are effective.


We not only track the county positivity rate, we disaggregated the zip code data to find out the actual positivity rates affecting our families.  


  • 60.9% of our families live in zip codes with less than 1.9% positivity rates.  
  • 8.7% of our families live in zip codes with less than 5.5% positivity rates.
  • 13.03% of families live in zip codes with less than 20% positivity rates.
  • 16.84% of families live in zip codes with 23.4% positivity rates.
  • 0.53% of families live in zip codes with 29.3% positivity rates. 


Our system data of well below 10% absenteeism coupled with over 82% of our families living in zip codes that are below 20% positivity rates supports that we remain with our current model of onsite instruction. In communications with other superintendents in the area with populations similar to ours, changing our learning model now is unwarranted.  We will continue to monitor our system and county data.


Working together, we can keep our kids in school!
