In addition, the bill creates a 16-member commission to investigate the Parkland shooting and make recommendations to the Legislature.
Few, if any, senators were completely happy with the legislation.
Here's a look at the main issues on the table, and what to expect this week.
The "Marjory Stoneman Douglas High School Public Safety Act" gives the police more power to seize weapons from people deemed mentally unfit. The senate's Republican majority opposed the sweeping changes to the state's gun laws, and as a result they will not be included in Monday's final bill.
The young people and adults they're pulling along with them are vowing to keep the Never Again movement going and going after elected leaders they believe are not leading. Would I want to see this go further? "It truly is", said Galvano, who represents Manatee County and part of Hillsborough County in the Tampa area.
He clarified that the students' current goal may be achievable down the line, but it isn't right now, although school safety is.
The Senate spent almost eight hours on Saturday debating dozens of amendments to the 100-page bill before finally approving the legislation for a final vote on Monday.
The shooting reignited the nationwide issue of gun control, with numerous student survivors of calling for new restrictions on gun sales.
The Florida Senate voted to name a program that will allow some teachers to carry guns in schools after an assistant high school football coach who was killed in a February school shooting.
But something is different this time.
Many students, teachers and parents have expressed opposition to the program, as has Gov. Rick Scott.
"Under the amendment, proposed by Sen".
And the greatest threat to Democrats' support is the Marshal Program. I agree to work on it. No form. No shape.
Republicans who voted against the measure, most notably Sens.
Several Democratic members expressed concerns about potential unintended consequences of arming teachers and about the amount of discretion given to sheriffs to set the program's rules in each district.
Before passing the bill 20-18, the Republican-led Senate scaled down the plan for allowing teachers to be armed.
Representative Steny Hoyer, the second-ranking House Democrat, said the House floor should be opened to a wide-ranging debate on gun measures.
The Legislature wraps up its annual session on Friday. The bill also bans "bump stocks" that allow semiautomatic weapons to fire more rapidly; increases the minimum age to buy a rifle from 18 to 21 and imposes a three-day waiting period on all gun purchases. "We don't want a veto of the bill because there is just too much good stuff in there for our schools, and for our students and families that need that, especially in Parkland".
The Senate bill also provides almost $400 million to pay for various school safety and mental health initiatives.
After they vote it will go to the house for a vote where it will also face opposition and debate.
