Some schools offer discounts to families who enroll more than one child. Inquire as you are going through the application process. There may be a waiver of fees and/or discounted tuition. There are sometimes deeper discounts for each child of the same family enrolled in a school at the same time.
Inquire during the application process whether the school offers scholarships. These may be full or partial scholarships. Schools may offer scholarships based on financial need, or they may award academic, music or sports scholarships. The school's office of financial aid can often assist you in finding funding sources.
Local organizations such as Elks' Clubs, Lions' Clubs, Rotary Clubs, women's clubs, churches and business groups may offer scholarships for which K-12 students are eligible. Sometimes they run ads in newspapers and bulletins, but it's smart to call and ask. That way, you won't miss deadlines, and you'll have an opportunity to ask some questions about the application process.
School choice programs, available in some areas, offer tax breaks for tuition and/or tuition vouchers so your child can attend private school. Call the office of your local school district to find out if this is an option.
There are plenty of websites that promise free money for private school education. Be wary of those. Federal programs have the domain extension .gov. State agencies have the state abbreviation plus .us. Although there are legitimate sites with .com and .org addresses, there are scammers out there, so use caution. Some sites may offer a bit of free advice, then ask you to pay for further information. Stay away from those. Legitimate funding sources do not charge you for information.
Every grant is a little bit different, so be sure to follow the application guidelines closely. Organizations usually have many applications to look at, so errors or omissions may disqualify your application immediately and you may not be told the reason. Make sure the information is correct to the best of your knowledge. Provide supporting documentation as required. Some organizations require that you use postal mail, while others accept, or even require, an electronic submission. Check the rules, and be sure you're in plenty of time to meet deadlines.
