TK vs. Pre-K:
Frequently Asked Questions

What is Transitional Kindergarten (TK)?

Transitional Kindergarten, or TK, is a public school program in California for children who meet state age eligibility requirements. TK follows a public school calendar and is part of the K–12 system.

​

TK programs operate within elementary schools and follow district structures, schedules, and policies.

​

What is Pre-K at Strata?

Pre-K at Strata is a private early learning program for children ages 4–5, designed to support children in the year before kindergarten through developmentally responsive, inquiry-driven learning.

​

Our Pre-K program is age-aligned with TK but operates independently from the public school system.

​

What are the main differences between TK and Pre-K?

Both TK and Pre-K can be strong options for families. The differences are primarily structural, not philosophical.

 

Schedule and Day Length

• TK typically follows a school-day schedule rather than a full-day program.

• Many TK programs do not offer on-site extended care.

• Strata offers full-day programming and extended-day options to support working families.

 

Rest and Downtime

• TK programs generally do not include rest or nap periods.

• Pre-K at Strata includes age-appropriate rest or quiet time, recognizing that many 4- and 5-year-olds still benefit from downtime.

 

Bathroom Independence

• TK classrooms require children to be fully independent in the bathroom.

• Strata supports children who are still developing bathroom independence, with staff assistance provided as needed.

 

Environment and Group Size

• TK classrooms are part of an elementary school setting and may be larger.

• Strata offers smaller group sizes and early learning environments designed specifically for this age group.

 

Approach to Learning

• TK follows district curriculum frameworks and pacing.

• Pre-K at Strata follows a developmentally responsive, inquiry-based approach that allows learning to deepen over time rather than move through fixed benchmarks.

 

Will Pre-K prepare my child for kindergarten?

Yes.

 

Preparation looks different than early academics alone.

 

At Strata, kindergarten readiness includes:

• Confidence and independence

• Strong language and communication skills

• Collaboration and problem-solving

• Emotional regulation and flexibility

• Curiosity, persistence, and comfort with challenge

 

These skills consistently support a successful transition into kindergarten, whether children enter public or private schools.

​

Is TK more “academic” than Pre-K?

Not necessarily.

 

TK reflects school-based structures because it is part of a public school system. Pre-K at Strata prioritizes how children learn rather than how early academics are introduced.

​

Research and experience show that children who develop strong foundational learning habits are well-positioned for academic success later.

​

How should families choose between TK and Pre-K?

The right choice depends on:

• Your child’s developmental needs

• Your family’s schedule

• Your values around learning and care

• Your child’s readiness for a school-based environment

 

Some children thrive in TK. Others benefit from an additional year in a developmentally responsive early learning setting.

​

Both paths can lead to successful kindergarten experiences.

​

Why do some families choose Pre-K instead of TK?

Families often choose Pre-K when they value:

• Full-day care and consistent routines

• Smaller group sizes and individualized attention

• Purposeful pacing that supports confidence and deeper understanding

• Strong foundations in communication, problem-solving, and collaboration

• Learning environments designed specifically for early childhood development
