Back-to-school season brings new teachers, new classrooms, new schedules and the return of routines that have been on vacation nearly as long as the students. For families, it is also a good time to review some of the basic safety rules that can easily get rusty during the summer months.

Those conversations should change as children grow. A kindergartner waiting for a school bus needs very different instructions than a middle school student walking home with friends, while a high school senior driving to school has another set of responsibilities entirely. The goal is not to give children a long list of things to fear, but to give them practical rules they can remember, practice and use when a parent or trusted adult is not immediately beside them.

Kindergarten through third grade

For the youngest students, repetition is especially important. Children in kindergarten through third grade should know their full name, home address and at least one parent's or guardian's phone number. They should also understand who they can ask for help, including teachers, school staff, police officers and other trusted adults, and they should know that 911 is used for emergencies involving police, fire or medical help. Parents can practice this information casually in the car, at dinner or while getting ready for school until the answers become familiar.

Young children should also know exactly who is allowed to pick them up from school, daycare, activities or the bus stop. If someone unexpectedly says a parent sent them, the child should stay with a teacher, bus driver or another trusted adult until the change can be confirmed. Some families may also choose to establish a simple family password for unexpected pickups, but children should understand that the safest option is still to stay with a trusted adult while plans are verified.

School bus safety should remain simple and consistent. Children should wait well away from the curb or roadway, avoid running or pushing near traffic and wait until the bus has completely stopped before approaching it. When leaving the bus, they should remain where the driver can see them, never walk behind the bus and never run back toward it for a dropped backpack, paper or other item without first getting the driver's attention.

Children who walk to school should practice the route with an adult before they are expected to handle it independently. Sidewalks, marked crosswalks and crossings supervised by crossing guards should be used whenever possible, and children should stop before entering the street, look left, right and left again, then continue watching traffic while crossing. One of the most important lessons is that seeing a vehicle does not mean the driver has seen the child, so children should make sure traffic has stopped before stepping into the roadway.

Bicycles bring another set of simple rules. Helmets should be worn every time, routes should be familiar and children should avoid shortcuts through alleys, parking lots, wooded areas or unfamiliar property. Walking or biking with siblings, friends or a group can add another layer of safety, especially for younger students.

Stranger safety can be taught without making children afraid of everyone they meet. Young students should understand that they do not need to accept rides, gifts or invitations from people they do not know, and that they should move toward a trusted adult if something makes them uncomfortable. The basic message can remain simple, know where you are supposed to be, know who is supposed to pick you up and tell a trusted adult if something does not feel right.

Third through fifth grade

By third, fourth and fifth grade, many students begin asking for more independence, and parents can start shifting from simply giving rules to explaining why those rules exist. Upper-elementary students who walk or bike can take more responsibility for knowing their route, obeying traffic signals and paying attention to their surroundings. At this age, phones, earbuds and headphones can also become a distraction, so devices should be put away while crossing streets, biking or moving through busy school parking lots.

This is also a good age to talk about what happens when the normal plan falls apart. A child should know what to do if the bus is missed, nobody is home, a house key is lost, a garage keypad does not work or a phone battery dies. Families should establish a Plan B and, when possible, a Plan C, including a trusted neighbor, nearby relative or family friend the child is allowed to contact.

A child who cannot get into the house should know exactly where to go rather than wandering the neighborhood, sitting outside alone or attempting to solve the problem by going somewhere unfamiliar. Parents should make sure backup adults know they are part of the plan, and children should know the names, locations and phone numbers of those people.

When younger children are home alone

For some families, the return to school also means a child may arrive home before a parent finishes work. That situation deserves its own safety plan, particularly for children in the upper-elementary years.

Minnesota does not establish one single age at which every child is automatically ready to stay home alone. Dakota County supervision guidelines advise that children younger than eight should not be left home alone, while children ages eight through 10 may be able to remain home alone for less than three hours depending on maturity and circumstances. The county also advises that children younger than 11 should not be responsible for babysitting other children.

Age, however, is only one part of the decision. A child who follows household rules, remains calm during minor problems and feels comfortable being alone may be ready for a short period without an adult, while another child of the same age may not be. Parents can begin with short trial runs while remaining nearby, then talk afterward about what happened, what felt uncomfortable and what questions came up.

Children who spend time alone after school should have a consistent arrival routine. That may include going directly inside, locking the door, putting the house key in its designated place and immediately calling or texting a parent to say they are home. A predictable routine makes it easier for both the child and parent to recognize when something is not going according to plan.

Families should also establish rules about what children may do while they are alone. For younger children, kitchen rules might mean cold snacks or microwave foods only, with no use of the stove, oven, sharp knives or other appliances. Parents should decide whether children may go into the yard, visit a friend, ride a bike or invite anyone into the house, rather than leaving those decisions to be made in the moment.

Children who are home alone should also understand that they should never advertise that fact. They should not tell someone at the door, on the telephone, in a text message, during an online game or on social media that no adult is home. If someone knocks or rings the doorbell, the simplest rule for younger children may be to leave the door locked unless a parent has specifically instructed otherwise.

Emergency plans should be practiced before they are needed. Children should know what to do if there is smoke, a fire alarm, a carbon monoxide alarm, severe weather, a power outage, an injury or someone trying to enter the home. If there is smoke or fire, the first job is to get outside and remain outside, not to go back for a phone, backpack, toy or pet.

Families should also designate at least one nearby adult who can respond quickly if a parent cannot immediately get home. Emergency information can be placed on the refrigerator, bulletin board or another easy-to-find location, including the child's address, parent phone numbers, trusted neighbors and backup contacts. Children should still learn their address and important phone numbers from memory, but a written sheet provides another layer of backup when a child is nervous or frightened.

Parents should also make a clear distinction between staying home alone and babysitting. A child who is mature enough to spend an hour alone after school is not automatically ready to supervise a younger brother or sister. Caring for another child adds responsibility, judgment and emergency decisions that are very different from simply managing oneself for a short period.

Sixth through eighth grade

Middle school brings another major shift in responsibility. Students in sixth through eighth grade often have more freedom, more complicated activity schedules and, increasingly, a phone that connects them to friends throughout the day. Parents may give them more independence, but expectations about communication, transportation and online behavior should remain clear.

Phones can be useful safety tools, but they also introduce new risks. Middle school students should understand that photographs, messages and videos can travel far beyond the person they originally intended to receive them, and deleted material may still exist through screenshots, saved messages and other devices. Students should be cautious about sharing schedules, exact locations, home addresses or information showing when nobody is home.

Parents should also talk openly about online friends and cyberbullying. Students should know they can come to a parent, teacher, counselor or another trusted adult if they receive threatening, humiliating or inappropriate messages, and the same applies if they see another student being targeted. The goal is to make asking for help feel normal before a problem becomes serious.

Ride safety becomes more important during the middle school years as students begin traveling more frequently with friends, teammates and older siblings. Families should establish who is allowed to provide transportation, rather than assuming any familiar teenager or adult is automatically an approved driver. Students should know that if transportation plans change, they need to communicate that change before getting into another vehicle.

Middle school students are also old enough to take greater responsibility for noticing what is happening around them at school. If they hear a threat, see someone attempting to enter a secured area or notice something that seems concerning, they should tell an adult rather than assuming someone else will handle it. Independence should come with accountability, including letting parents know where they expect to be, who they are with and when plans change.

Ninth and 10th grade

By ninth and 10th grade, many families are adding one of the largest new safety responsibilities of the teenage years, driving. Freshmen and sophomores may be getting permits, licenses and access to family vehicles, while also managing sports, jobs, practices and social activities with much less direct supervision than they had just a few years earlier.

New drivers should practice the route to school before they are expected to navigate it during the morning rush. Knowing entrances, parking areas, intersections and pickup zones can reduce confusion, while leaving home a few minutes early can remove the temptation to hurry. School parking lots are busy places filled with pedestrians, inexperienced drivers, buses and parents trying to get somewhere at the same time.

Phones should be put away while driving, everyone in the vehicle should wear a seat belt and speed limits should be followed, particularly in school zones. Friends inside the vehicle can be a major distraction for an inexperienced driver, so parents should discuss passenger expectations before the first unsupervised trip. Families should also know the passenger restrictions that apply to newly licensed drivers.

Teenagers should understand that calling home for help is always preferable to making a dangerous decision. If weather becomes unsafe, a driver is too tired, transportation plans fall apart or a student finds themselves in a situation where they do not feel safe, contacting a parent or trusted adult should be treated as the responsible choice rather than something that will automatically result in punishment.

11th and 12th grade

By junior and senior year, students are approaching adulthood, and many drive themselves to school, work part-time jobs, participate in activities and make dozens of decisions each day without a parent nearby. The safety conversation becomes less about instructions and more about expectations, judgment and responsibility.

Older students should continue following the same driving rules that mattered when they first earned a license. Seat belts, phones, speed limits and distractions do not become less important simply because the driver has another year or two of experience. Students who drive friends should also understand that the driver is responsible for the vehicle, regardless of who is encouraging them to hurry, check a message or take an unnecessary risk.

Parents can also remind older teens that independence includes knowing when to speak up. If something appears wrong at school, a threat is made, an unfamiliar person is trying to enter a secured area or a friend appears to be in danger, telling an adult is not overreacting. Older students are often in a position to notice problems younger children may not recognize.

Parents and drivers have homework, too

Back-to-school safety is not only the responsibility of students. Drivers should expect morning and afternoon traffic patterns to change when school begins, with buses making frequent stops, crossing guards returning to intersections and children once again walking and biking through neighborhoods. Slowing down, putting the phone away and leaving a few extra minutes can make the start and end of the school day safer for everyone.

Extra attention is especially important around crosswalks, school buses and school pickup areas. Parents dropping children off should follow the school's designated traffic pattern rather than creating a shortcut or unexpected stop simply because it appears faster. A few extra minutes spent waiting in line is a minor inconvenience compared with introducing another unpredictable vehicle movement around children.

Perhaps the most useful back-to-school safety lesson is that the rules should grow along with the child. A first-grader may need to memorize a parent's phone number and learn where to stand while waiting for the bus. A fourth-grader may need a detailed plan for arriving home before Mom or Dad, a seventh-grader may need reminders about online privacy and rides with friends, and a sophomore may need firm rules about passengers and phones in the car.

By senior year, the conversations may be shorter, but they are no less important. Being nearly an adult does not make anyone immune to distraction, poor judgment or an unexpected situation.

Families can make those conversations easier by writing down the important information, particularly for younger children who may spend time alone after school. An After-School Safety Sheet can include the child's address, parent and emergency contacts, school information, backup plans and household rules, then be placed somewhere the child can easily find it.

The form should be treated as a backup, not a substitute for practice. Children should still be able to say their full name and home address without reading the sheet, know which adults they can call and understand what to do when the normal routine does not go according to plan.

The details change as children grow, but the goal remains the same, give students enough knowledge, practice and responsibility to make a safe decision when they eventually have to make it on their own.
