Prom 2019

Prom will be held on Friday, April 26, at The Rosemont Convention Center.  The cost is $75 per person. Please note each student AND each guest will need to fill out their own permission form.   Due to reservation requirements, unfortunately we will not be able to offer refunds after April 19th.  Additionally, no refunds will be issued to students in the event of a disciplinary action or an attendance issue on the day of prom, which results in the student's inability to attend prom.

While tickets for the Prom itself are always available to any eligible CG student (as an individual) or with a date, sign up for our wildly popular (and safe) Post-Prom activity supported by our Booster Club is unfortunately limited.  We will be selling post-prom tickets on a first come and first served basis, prioritizing as many seniors as possible attending their last Prom and Post-Prom with us.  Below are the details of the process that allow for the aforementioned prioritization and also minimize attendance issues during the school day.  In the past four years, Post-Prom has NOT sold out; all students who wanted to, were able to attend this event.  

Beginning the evening of Tuesday, April 9 from 6 PM to 9 PM Cary-Grove High School Seniors only, may sign up for Prom and Post-Prom in the Media Center on this date.  Senior Cary-Grove students attending with another Senior Cary-Grove student will register from 6 PM until 7:30 PM, the Senior CG students attending with anyone other than a Cary-Grove senior student will register from 7:30 to 9:00 PM.   If arriving after 7:30 PM, any CG senior/CG senior must go to the back of the line.  

On the evening of Wednesday, April 10 from 6 PM to 8 PM any CG Junior and their date or CG Senior and their date (if they did not sign up on April 9) may sign up for Prom (and Post-Prom, until sold out).  On this date there will be no priority given to CG seniors.   Additional ticket sale dates are shown in the table below.

Prior to registration, all students and guests must EACH complete a permission form, have an online payment receipt or a check payable to CGHS, or cash along with all paperwork approved for guests.

Any change request to prom arrangements after the April 9 and 10 sale dates will require a $10 processing fee.

Eighty Business Law Students Participate in Mock Trial

Eighty Crystal Lake South and Cary-Grove High School students participated in a Mock Trial on December 7. Students prepared, planned, and organized this event by working with State’s Attorney Patrick Kenneally and his office staff. Each year the cases are written by the Illinois State Bar Association for High School Mock Trials. Students from both Crystal Lake South and Cary-Grove took on roles of defense and prosecutor attorneys, as well as witnesses and jurors from each school.

Student attorneys and witnesses prepared with a State's Attorney for one class period prior to the event and for about one hour before the event. During the trial, a State's Attorney sits with them and guides them during the opening statements, direct examination and indirect examination of witnesses as well as during the closing statements. This year, the Assistant State’s Attorneys Theresa V. Kaman and Brette Dunbar helped with Cary-Grove, and Michelle Clesceri and Bobby Zalud helped with Crystal Lake South.

“This has been a very successful and rewarding learning experience for our students and we hope to continue it in the future,” said Theresa Miller, Cary-Grove’s Business Education Teacher.

For the past three years, District 155 Business Law classes have been participating in Mock Trials at the McHenry County Government Center.

Tax Levy Proposal Saves Taxpayers at Least $1.7 Million Per Year
District 155’s Board of Education approved a tentative tax levy proposal that will save taxpayers at least $1.7 million per year on November 20.

District 155 proposed an estimated increased tax levy, however the district will pursue a state Property Tax Relief Grant which provides school districts an opportunity to lower the burden on local taxpayers. The district will permanently reduce its operating levy to flat or lower after the state notifies the district if it is awarded the grant in late January.

“We want our taxpayers to know we’re listening to them, and we understand their concerns about their tax bills. This year’s tax levy process, despite an estimated increase, will result in a savings to our taxpayers every year moving forward,” said Jeremy Davis, assistant superintendent of finance and operations.

The estimated savings for a $200,000 house is $53.14 for the District 155 portion of the tax bill. The tax rate for District 155 has dropped three consecutive years, and the tax rate is 12.7 percent less than it was in 2014.

“As one of the top performing districts in McHenry County, District 155 will have levied flat two of the past four years. We understand the impact great schools can have on local property values, and we’re proud to be part of a community that values education,” said Adam Guss, Board of Education president.
