The rules will apply to unvaccinated students in close contact with someone who tested positive for COVID-19, or students and staff instructed to quarantine or isolate after testing positive.

This is the first time CPS families have been invited to weigh in on the calendar, CEO Pedro Martinez said in the letter sent out Thursday.

CPS reported 439 students and 121 staff members tested positive for COVID-19 last week, a drop of about 60 percent compared to two weeks ago.

About 49 percent of students from 5 to 17 are vaccinated, but several schools on the South and West sides had fewer than 10 percent of their student population fully vaccinated.

The district could do away with its ranking system for the highly sought-after schools by the 2023-2024 academic year.

Under the proposed calendar, the 2022-2023 academic year would kick off on Aug. 22 and end June 7.

The district has so far spent only 12 percent, or $62.9 million, on a half-billion initiative designed to help students bounce back from COVID disruption.

Vaccination rates at Chicago Public Schools range from just 6.7 percent of students to over 90 percent.

Over the past six years, Trevor Nicholas’ student ensembles have premiered works at the Lyric Opera of Chicago, the Chicago Symphony Orchestra, the Harris Theater and Wrigley Field.

In December, only 5.4 percent of Dunne students were fully vaccinated. But in the past few months, the school has seen an increase in uptake to 42.3 percent, close to CPS’ overall average.
