There’s No Wrong Answer—But There Are Important Differences
If you’re a parent in San Diego weighing childcare options, you’ve probably found yourself comparing three paths that sound similar but work very differently: home daycare, Center Based Care, and Transitional Kindergarten (TK).
Each one has strengths. Each one has limitations. And the right choice depends on your child’s age, your family’s schedule, your priorities around learning and socialization, and what’s available in your area.
This guide walks through what each option actually looks like day to day, how they differ in structure, cost, and learning outcomes, and how to think about the decision in a way that gives you confidence rather than anxiety.
Home Daycare: What It Is and Who It’s Best For
A home daycare (sometimes called family childcare) is a small program operated out of a caregiver’s home. In California, a small family childcare home can serve up to 8 children, while a large family childcare home can serve up to 14 with an assistant.
What a typical day looks like
Home daycares tend to have a more flexible, home-like rhythm. Children of mixed ages play together, meals are often prepared on-site, and the environment feels intimate. There may be learning activities, but the structure varies widely depending on the provider. Some home daycares follow a curriculum; many do not.
Strengths
- Smaller group size—ideal for infants and young toddlers who thrive in quieter environments
- Mixed-age setting can benefit children who learn from watching older peers
- Scheduling tends to be more flexible, including nontraditional hours
- Often lower cost than center-based care
Considerations
- Quality and consistency vary significantly from one provider to the next
- Educational programming and teacher qualifications are not standardized
- If the provider is sick or takes vacation, families may not have backup care
- Less redundancy in staffing and oversight compared to center-based programs
Center Based Programs: What It Is and Who It’s Best For
A Center Based Program (or early learning center) is a licensed facility designed specifically for young children, with dedicated classrooms for all age groups from infant through 5. Programs may be full-day or part-day, and most follow a defined curriculum that balances structured learning with play.
What a typical day looks like
Days have an intentional rhythm: circle time, small-group activities, outdoor play, creative projects, meals and snacks, rest time, and free play. Children are grouped by age and developmental stage, which allows teachers to tailor activities to what each group needs.
At Kids Care Club, for example, our toddler classrooms focus heavily on language development, sensory exploration, and building comfort with routines, while our preschool classrooms introduce early literacy, math concepts, and more complex social dynamics.
Strengths
- Most consistent daily structure among the three options
- Teachers typically required to have early childhood education credentials and experience working with the age group
- Age-matched peer groups support developmentally appropriate socialization
- Built-in staffing redundancy—if one teacher is absent, the program continues
- Most directly prepares children for the structure and expectations of elementary school
- All staff are CPR and First Aid certified
- Research-based curriculum aligned with early learning standard
Considerations
- Typically the most expensive option, especially for full-day, high-quality care
- Hours may be less flexible than home daycare (though many programs offer extended care)
- More structured environment may feel like a bigger adjustment initially
Transitional Kindergarten (TK): What It Is and Who It’s Best For
Transitional Kindergarten is a free, public school program for children who turn four by September first of the school year. With California’s universal TK expansion, all four-year-olds are now eligible for the 2026-2027 school year.
What a typical day looks like
TK classrooms are located in public elementary schools and follow a modified kindergarten curriculum designed for younger children. The school day typically runs from approximately 8:00 a.m. to 2:30 p.m., with activities including early literacy, math readiness, science exploration, art, and physical activity, delivered by a credentialed teacher with a classroom aide.
Strengths
- Free—the biggest financial advantage for families with four-year-olds
- School-based setting familiarizes children with elementary school routines
- Credentialed teachers with classroom aides
- Children who attend TK often enter kindergarten with stronger school-readiness skills
Considerations
- Follows the public school calendar—no care during summer, winter break, spring break, or teacher workdays
- Shorter school day means most working parents need wraparound care
- Bigger group setting that may feel less intimate than smaller programs
- Before-school and/or After-school care that includes older children may feel overstimulating or overwhelming for younger TK students.
- Not available for children under four—not a replacement for infant, toddler, or young preschool care
- School environment is fundamentally different from a preschool setting
What Parents Want to Know—And How KCC Answers
1. “Which option is best for my two- or three-year-old?”
At this age, TK isn’t available, so the choice is between home daycare and preschool. Children between two and three are developing language, social skills, and independence at an extraordinary rate. A structured preschool environment with trained teachers and age-matched peers supports this development in ways that are difficult to replicate in other settings.
2. “My child is four. Should I do preschool or TK?”
This depends on four factors: whether you need full-day care (preschool offers longer hours), whether cost is a primary concern (TK is free), whether continuity matters (staying at a familiar school vs. transitioning), and your priorities around individualized attention. Many Kids Care Club families keep their four-year-old enrolled because of the relationships, full-day schedule, and the larger vs smaller setting on campus. smaller class sizes.
3. “Will my child be ready for kindergarten?”
Yes—all three options can contribute to kindergarten readiness, but the depth differs. Quality preschool programs with credentialed teachers and research-backed curricula consistently produce the strongest outcomes in language, social-emotional development, and self-regulation. At KCC, our curriculum is specifically designed to build kindergarten readiness across every developmental domain.
4. “What if I use TK for the school day but need more care?”
Many families combine TK with wraparound care at a preschool or childcare center. Kids Care Club offers after-school programs specifically designed for TK students, so your child gets the benefit of both environments. At Kids Care Club, your child stays in the care of the same familiar primary teacher/s and the same group of children throughout the day so that your child get the comfort of consistency while at school.
What Real Parents Say After Comparing Options
| “Both my daughter and son attend KCC. I love that the values and manners we teach at home are continued during their day at KCC. The structure, routine and educational aspects at KCC have helped my daughter to develop so many skills, including advancing educationally, working with others, addressing conflict and building friendships.”
— Megan S., KCC Parent |
| “KCC is great! High quality teachers coupled with an outstanding curriculum make this a wonderful child development center. Management, teachers and staff all make an effort to know the families personally. It feels like we are leaving our child with family. The teachers go over-and-beyond what is required to ensure the best quality care and development—they genuinely care and enjoy what they do.”
— Rochelle S., KCC Parent |
| “KCC has been invaluable to our children’s development. Having a specific curriculum for our children to learn from is clearly noticeable in their development. We have been impressed with our son’s vocabulary, thinking skills, and how he expresses himself, which is difficult for us to work on at home with a 2 parent working family. Equally important, his social skills and confidence in himself would not be where they are had it not been for KCC.”
— Frank V., KCC Parent |
How Learning Outcomes Differ
- Home daycare: Nurturing, stable care possible, but educational outcomes depend entirely on the individual provider’s training. No standardized curriculum requirement.
- Center Based Care: Programs with credentialed teachers and research-backed curriculum offer the most intentional developmental programming. Children consistently show stronger language, social, and self-regulation skills entering kindergarten.
- TK: Strong academic readiness with school-skills focus, but larger class sizes may limit depth of social-emotional and individualized support.
Questions to Ask When Touring Any Childcare Program
Use these to guide your decision, no matter which type of program you’re evaluating:

Frequently Asked Questions
What is the difference between home daycare and preschool?
Home daycare is a small childcare program operated out of a caregiver’s home, typically serving 8 to 14 children of mixed ages with flexible scheduling and a home-like environment. Preschool is a licensed early learning center with age-grouped classrooms, credentialed teachers, and a structured curriculum balancing learning with play. The main differences are group size, educational consistency, teacher qualifications, and the level of daily structure.
Is TK the same as preschool?
No. Transitional Kindergarten is a free public school program for four-year-olds, located in elementary schools and taught by credentialed teachers using a modified kindergarten curriculum. Preschool is a separate, typically tuition-based program serving a wider age range including Pre-K/TK and operating independently . Private preschool offers a more personalized, relationship-based experience. Children receive more one-on-one attention and learning tailored to their individual needs.
Beyond academics, private preschools nurture the whole child by supporting social, emotional, and cognitive growth, often with full-day, year-round programs that provide consistency and stronger teacher-child connections.
Which childcare option offers more structure?
Preschool programs typically offer the most consistent daily structure, with intentional routines including circle time, small-group activities, outdoor play, creative projects, meals, rest time, and free play. TK provides structured learning within a public school format and shorter day. The structure of home daycare varies significantly by provider.
How do learning outcomes differ between daycare, preschool, and TK?
Children in quality preschool programs with credentialed teachers and research-backed curriculum consistently show stronger language development, social skills, and self-regulation entering kindergarten. TK provides strong academic readiness focused on school skills, but with larger class sizes, individualized support may be more limited. Home daycare outcomes depend on the individual provider’s training and approach.
Is home daycare cheaper than preschool in San Diego?
In most cases, yes. Home daycare typically costs $1,200 to $1,800 per month for full-time care in San Diego, while quality preschool programs range from $1,800 to $3,000 or more depending on the program and child’s age. TK is free as a public school program, though families often incur costs for before- and after-school wraparound care.
What age is best for preschool vs. TK?
Preschool serves children from infancy or age two through five, making it suitable across a wide developmental range. TK is designed specifically for four-year-olds. For children under four, preschool or home daycare are the available options. At age four, the choice depends on schedule needs, class size preference, cost, and existing relationships at the child’s current program.
Do I need after-school care if my child is in TK?
Most families do. The TK school day runs approximately 8:00 a.m. to 2:30 p.m. and follows the public school calendar, including closures for summer, winter break, spring break, and teacher workdays. Many preschools and childcare centers, including Kids Care Club, offer wraparound care specifically designed for TK and kindergarten students.
How do I decide between Center Based Care and TK for my four-year-old?
Consider five factors: whether you need full-day care (preschool offers longer hours), whether cost is a primary concern (TK is free), how your child handles larger groups whether continuity matters (staying at a familiar school vs. transitioning), and your priorities around individualized attention versus school-based preparation.
