What is the difference between 3-K and UPK in NYC?

3-K (3-K for All) is NYC's free preschool program for 3-year-olds. UPK (Universal Pre-K) is the free program for 4-year-olds. Both run about 6 hours and 20 minutes per day during the school year, with some sites offering extended day options.

Can I combine 3-K or UPK with private daycare?

Yes. Many Greenpoint families use 3-K or UPK for the school day (about 8am-2:30pm) and then transfer to a private program for afternoon care. Some daycares offer after school pickup and enrichment programs for this purpose.

Is private preschool worth the cost compared to free 3-K?

It depends on your priorities. 3-K covers the basics for free. Private preschools offer longer hours, smaller class sizes, enrichment programs (music, art, languages), specialized curriculum, and more individual attention. Many families find the value in a private program that includes everything rather than piecing together care from multiple sources.

NYC 3-K vs UPK vs Private Preschool: What Greenpoint Parents Need to Know

Published April 7, 2026 by Gifted and Talented Kids

You've probably heard that NYC offers free preschool. And it does. 3-K for 3-year-olds, UPK for 4-year-olds. Zero tuition.

But "free" comes with trade-offs. Limited hours. Larger class sizes. A lottery system where your first-choice school is never guaranteed. And for working parents, 6 hours of care rarely covers a full workday.

This guide compares 3-K, UPK, and private preschool side by side so you can make an informed decision for your family in Greenpoint.

The Side-by-Side Comparison

Factor	3-K (Age 3)	UPK (Age 4)	Private Preschool
Cost	Free	Free	$1,800 - $3,200/mo
Hours	6 hrs 20 min	6 hrs 20 min	8-10 hours
Calendar	Sept - June	Sept - June	Year-round (most)
Class Size	15-18 kids	18-20 kids	8-15 kids
Teacher Ratio	1:6 to 1:9	1:9 to 1:10	1:4 to 1:6
Meals	Free lunch	Free lunch	Included (premium)
Enrichment	Limited	Limited	Music, art, dance, languages, STEM
Application	Lottery (MySchools)	Lottery (MySchools)	Direct enrollment
Extended Day	Some sites	Some sites	Standard
Summer	Some sites	Some sites	Yes (most)

What Is 3-K for All?

NYC's 3-K program launched in 2017 to provide free, full-day preschool for every 3-year-old. In Greenpoint, a handful of sites participate. You apply through MySchools NYC (myschools.nyc) starting in late winter for fall enrollment.

What you need to know:

Application is a lottery. You rank your preferred schools, but placement depends on seat availability.
Standard day runs roughly 8:00 AM to 2:20 PM. Some sites offer extended day until 6:00 PM.
School year only (September through June). No summer unless the site offers it separately.
Curriculum follows NYC DOE guidelines. Quality varies by site.
Transportation is not provided for most 3-K programs.

What Is UPK (Universal Pre-K)?

UPK has been available in NYC since 2014 for all 4-year-olds. Greenpoint has several UPK sites, including within public schools and community-based organizations.

The structure is similar to 3-K: lottery application, 6-hour school day, school-year calendar. The main difference is that UPK is more widely available, so your chances of getting a nearby placement are better.

When Private Preschool Makes Sense

Private preschool fills these gaps:

Full workday coverage. 3-K/UPK ends at 2:20 PM. If you work 9 to 5, you need afternoon care anyway.
Year-round calendar. Summer gap? Private programs run through July and August.
Smaller classes. 8-15 kids vs 18-20. More individual attention means faster development.
Enrichment included. Music, dance, art, Spanish, STEM. No need to book separate classes on evenings and weekends.
Specialized curriculum. Montessori, Multiple Intelligences, Reggio Emilia. Tailored to how your child learns best.
Guaranteed spot. No lottery. You apply, you tour, you enroll. Done.

The Hidden Costs of "Free" Preschool

3-K and UPK are free. But the real cost of care for a working parent looks different.

If your 3-K site runs 8:00 AM to 2:20 PM:

Afternoon babysitter (2:30 PM to 6:00 PM): $18-25/hour, roughly $1,400-1,950/month
After school program (if available): $400-800/month
Summer camp or separate care (June-August): $2,000-4,000 total

Add it up: "free" 3-K plus afternoon care plus summer camp can cost $2,000-3,000/month when averaged across the year. That's the same as a private program that covers it all.

Can You Combine 3-K/UPK With Private Care?

Yes, and many families do. The typical setup:

Morning: child attends 3-K or UPK (8:00 AM to 2:20 PM)
Afternoon: pickup by private daycare, nanny, or after school program

This works well if:

Your 3-K/UPK site is near your afternoon care provider
You can coordinate pickup logistics
Your afternoon program offers the enrichment you want

At Gifted and Talented Kids, our After School Enrichment program (ages 5-7) is designed for this purpose. We also offer full-day programs for ages 2-5 if you prefer one location for the entire day.

Our Recommendation

There's no universally right answer. It depends on your schedule, budget, and priorities.

Budget is the top priority? Apply for 3-K/UPK. Use a nanny share or family member for afternoon hours.
Need full-day, year-round care? A private program is simpler and often comparable in total cost.
Want enrichment and specialized curriculum? Private programs include it. Public programs generally don't.
Want G&T test preparation? No public 3-K/UPK program specifically prepares for the NYC Gifted and Talented assessment. Some private programs do.

Full-Day, Year-Round, Enrichment Included

Gifted and Talented Kids covers the full workday with meals, enrichment, and a curriculum built on Howard Gardner's Multiple Intelligences. Ages 2-6 in Greenpoint.
