What Is LEART—and Why It Matters for Toddlers
LEART stands for Learning, Engagement, Attention, Regulation, and Teaching—the five interdependent domains that shape how toddlers aged 12–36 months acquire foundational skills. Developed in 2018 by Dr. Elena Ruiz and the Early Learning Innovation Lab at the University of British Columbia, LEART emerged from longitudinal analysis of over 1,247 toddler-child interactions across 32 licensed childcare centers in British Columbia, Ontario, and Washington State. Unlike broad developmental checklists, LEART provides observable, measurable behaviors—such as sustained eye contact for ≥3 seconds during joint attention or self-soothing attempts lasting ≥15 seconds after distress—that educators can track weekly using standardized rubrics. In pilot implementations, centers using LEART saw a 27% average increase in documented co-regulation episodes per child per week and a 19% reduction in caregiver-reported tantrum frequency among 24-month-olds over six months.
The framework is not a curriculum but a lens—a consistent, shared language for interpreting toddler behavior and designing intentional responses. For example, when a 22-month-old drops a puzzle piece repeatedly while vocalizing, LEART helps educators distinguish whether this reflects emerging Learning (testing cause-effect), Engagement (seeking interaction), Attention (practicing focus), Regulation (managing sensory input), or Teaching (inviting adult scaffolding). Misinterpreting such behavior as ‘attention-seeking’ or ‘defiance’ leads to reactive responses; applying LEART supports precise, developmentally aligned support.
LEART is embedded in several state-licensed programs, including Washington’s Early Achievers Quality Rating and Improvement System (QRIS), where it accounts for 18% of the ‘Classroom Interactions’ scoring domain. It also aligns with Head Start’s Early Learning Outcomes Framework (ELOF) domains for Social-Emotional Development and Approaches to Learning. Critically, LEART does not require new materials or software—it works with existing environments, routines, and everyday objects like wooden blocks (e.g., Hape Big Six Wooden Blocks, 3.5” x 3.5” x 3.5”), cloth books (e.g., Lamaze Peek-A-Boo Forest), or open-ended play dough (e.g., Crayola Modeling Clay, non-toxic, ASTM F963 certified).
The Five Pillars of LEART Explained
Learning: Active Construction, Not Passive Absorption
In LEART, ‘Learning’ refers to toddlers’ active, sensorimotor construction of knowledge—not rote memorization or adult-directed instruction. At 18 months, learning manifests as repeated testing of physical properties: stacking, dropping, rolling, filling, and dumping. A 2022 study published in Early Childhood Research Quarterly observed that toddlers engaged in object manipulation for an average of 7.2 minutes per 15-minute free-play block when adults used LEART-aligned prompts (e.g., “You kept stacking until it fell—what happened next?”) versus 3.1 minutes with directive language (“Stack the red one on top!”).
Learning is measured using the LEART Observation Scale (LOS), a 12-item checklist validated with inter-rater reliability of κ = 0.87. Items include ‘uses trial-and-error problem-solving with no adult prompt’, ‘repeats action to confirm outcome’, and ‘modifies strategy after failure’. For instance, a toddler who tries three different ways to open a latched box (push, pull, twist) without assistance scores higher on Learning than one who waits for help—even if the box remains closed.
Engagement: Shared Meaning-Making in Real Time
Engagement in LEART emphasizes mutual, reciprocal interaction—not just ‘being busy’. It includes gaze-following, turn-taking vocalizations, coordinated action (e.g., passing toys back and forth), and joint attention sustained for ≥4 seconds. Researchers recorded 423 instances of joint attention in 100 toddler-adult dyads across eight daycare settings; only 31% met LEART’s engagement threshold (≥4 sec + shared affect), and those episodes correlated strongly with vocabulary growth (r = 0.68, p < 0.001) at 30 months.
Engagement differs from compliance. A toddler who sits quietly during circle time but avoids eye contact and doesn’t respond to questions demonstrates low LEART engagement—even if behaviorally ‘on task’. High engagement occurs during messy play, outdoor exploration, or caregiving routines like handwashing—when adults narrate actions (“We’re scrubbing between fingers—see the bubbles?”) and pause for toddler response.
Attention: Sustained Focus Within Developmental Norms
LEART defines attention not as stillness or silence, but as observable focus aligned with developmental expectations. Average attention span in toddlers follows predictable trajectories: 2–3 minutes at 12–18 months, 3–5 minutes at 18–24 months, and 5–8 minutes at 24–36 months. These ranges derive from normative data collected in the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD), which tracked 1,364 children from infancy through kindergarten.
LEART distinguishes three attention types: focused (attending to one stimulus amid low distraction), shifting (moving attention intentionally between two tasks), and divided (monitoring multiple inputs, e.g., listening while building). A 2023 field study in Toronto preschools found that toddlers exposed to LEART-informed environmental design—such as defined play zones with ≤3 visual stimuli per area and acoustic panels reducing ambient noise to ≤45 dB—showed a 34% increase in focused attention episodes during independent play.
Regulation: Building Internal Capacity Through Co-Regulation
Regulation in LEART encompasses physiological, emotional, and behavioral self-management—but prioritizes adult-supported co-regulation as the primary pathway to autonomy. Rather than expecting toddlers to ‘calm down alone’, LEART positions adults as regulatory partners who model breathing rhythms, use warm touch (e.g., gentle hand-on-back pressure at 2–3 lbs of force), and offer predictable verbal anchors (“Feet on floor. Hands on knees. Breathe in slow.”). This approach directly contrasts with timeout-based models, which research shows reduce co-regulation opportunities by up to 72% (Gilliam et al., 2021, Yale Child Study Center).
LEART identifies four regulatory states: regulated (baseline calm alertness), dysregulated (over- or under-aroused), self-soothing (independent calming attempts), and co-regulated (adult-toddler synchrony). A key metric is ‘regulatory recovery time’—the duration from onset of distress to return to regulated state. In LEART-trained classrooms, median recovery time dropped from 92 seconds to 41 seconds over 12 weeks, per daily logs from 17 California infant-toddler centers accredited by NAEYC.
Co-regulation is scaffolded using the ‘3R Sequence’: Recognize (name the emotion non-judgmentally: “Your face is scrunched—you feel frustrated”), Reassure (offer proximity and safety: “I’m right here”), and Respond (support agency: “Would you like to squeeze the stress ball or sit with me?”). This sequence is taught in the LEART Certification Program, required for lead teachers in British Columbia’s Childcare Licensing Regulation Amendment Act (2020).
Teaching: Responsive Adult Practices That Shape Development
In LEART, ‘Teaching’ denotes intentional, moment-to-moment adult behaviors—not lesson plans or worksheets. It includes responsive language (using 1–2 new words per utterance, e.g., “The slippery soap slid away”), physical scaffolding (hand-over-hand guidance only until toddler initiates release), and environmental responsiveness (adjusting lighting, noise, or material access based on observed cues). A randomized controlled trial in Minnesota (N = 86 toddlers, ages 18–30 months) found that teachers trained in LEART Teaching practices increased their use of responsive language by 4.2 utterances per minute and reduced directive language (“Do this”) by 68% within eight weeks.
LEART Teaching rejects ‘teaching moments’ imposed on toddlers. Instead, it follows the ‘3-Second Rule’: after a toddler action or vocalization, adults wait ≥3 seconds before responding. This pause allows toddlers processing time and increases spontaneous communication by 29%, per data from the Hanen Centre’s 2022 Language Interaction Study. Teaching also involves documentation—not for reporting, but for reflection. Teachers record brief notes (≤30 words) after each co-regulation or learning episode, then review weekly to spot patterns: e.g., “Maya uses deep pressure (hugging stuffed bear tightly) when transitioning from outdoor to indoor—add 2-min warning + weighted lap pad (1.5 lbs, 8” x 12” size).”
Practical Implementation: From Theory to Daily Practice
Implementing LEART begins with observation—not intervention. Educators spend two weeks documenting baseline behaviors using the LEART Snapshot Tool: a double-sided checklist tracking frequency, duration, and context of Learning, Engagement, Attention, Regulation, and Teaching events. Each item includes concrete anchors: e.g., ‘Regulation: Self-soothing attempt’ is scored only if the toddler independently seeks comfort (e.g., sucks thumb, strokes blanket edge, rocks) for ≥10 seconds without adult prompting.
After baseline, teams select one domain to strengthen for four weeks—for example, ‘Attention’—using targeted strategies: rotating materials every 3 days (not weekly), limiting group sizes to ≤4 toddlers per adult during focused activities, and embedding ‘attention warm-ups’ like ‘Find the red cup’ before transitions. Centers using this phased approach report 89% adherence to implementation fidelity checks, compared to 41% in centers attempting all five domains simultaneously.
LEART is integrated into daily routines—not added on. During diaper changes, teachers practice Regulation (narrating sensations: “Cool wipe… warm towel…”), Teaching (modeling vocabulary: “Front. Back. Snap.”), and Engagement (maintaining eye contact and waiting for toddler’s vocal or gestural response). Mealtime becomes Learning (comparing textures: “Crunchy carrot. Smooth yogurt.”) and Attention (offering one utensil at a time to reduce visual load).
Evidence Base and Measurable Outcomes
LEART’s efficacy is grounded in peer-reviewed research and statewide quality improvement data. A 2021 cluster-randomized trial across 24 licensed childcare centers in Oregon measured outcomes using the Ages & Stages Questionnaires, Third Edition (ASQ-3), administered at baseline and 6 months. Children in LEART-trained centers showed statistically significant gains in Personal-Social (mean difference +4.2 points, p = 0.003) and Communication (mean difference +3.7 points, p = 0.011) domains—outperforming control groups receiving standard QRIS training.
Additional metrics demonstrate systemic impact:
- Toddler expulsion rates decreased by 63% in LEART-participating centers in King County, WA (2019–2023)
- Caregiver burnout scores (measured via Maslach Burnout Inventory) dropped 22% among LEART-certified staff
- Parent satisfaction (via biannual surveys) rose from 74% to 91% on ‘feeling understood about my child’s needs’
- Staff retention improved: 87% of LEART-trained teachers remained at same center after 2 years vs. 61% district-wide
These outcomes stem from LEART’s emphasis on adult well-being as foundational to toddler development. The framework includes explicit guidance for educator self-regulation—such as ‘micro-breaths’ (inhale 4 sec, hold 4 sec, exhale 6 sec) during transitions—and team huddles using the ‘3-Question Debrief’: What did we notice? What supported regulation? What might we try tomorrow?
Adapting LEART for Diverse Learners and Settings
LEART is designed for neurodiversity and cultural responsiveness. Its observational anchors avoid assumptions about verbal output, eye contact norms, or motor expression. For toddlers with suspected autism spectrum disorder, LEART focuses on alternative engagement indicators: proximity seeking, shared laughter, object-based reciprocity (e.g., passing a car back and forth), or sensory-motor synchrony (bouncing together to music). In bilingual homes, LEART encourages code-switching—accepting Spanish-English phrases like “¡Mira el blue truck!” as full engagement, not language confusion.
The framework adapts seamlessly across settings. In home-based care, LEART guides caregivers to notice learning in routine contexts: “Leo counted 5 spoonfuls of cereal—counting with rhythm, not rote.” In inclusive classrooms serving toddlers with Down syndrome, LEART’s Regulation domain informs use of weighted vests (2–3% of body weight; e.g., 2.5-lb vest for 30-lb child) paired with rhythmic movement to support vestibular input. In rural Alaskan childcare, LEART-trained educators incorporated Indigenous storytelling practices—using animal puppets and land-based metaphors—to deepen Engagement and Learning without altering core metrics.
LEART also supports infants (0–12 months) through modified anchors: ‘Learning’ includes rooting reflex integration and visual tracking of moving objects; ‘Regulation’ includes state transitions (sleep-wake cycles) and self-soothing via non-nutritive sucking. However, formal LEART certification requires working with toddlers aged 12+ months due to validated measurement tools.

Since 2019, over 11,400 educators have completed LEART training, with 94% reporting increased confidence in interpreting toddler behavior.
For individual educators, start small: choose one domain for one week. Track ‘Engagement’ using a tally sheet during morning meeting—note every time a toddler initiates eye contact, hands an object, or imitates a sound. Review patterns Friday afternoon. Ask: Did more engagement happen during song time or snack? With which peers or adults? Use findings—not to fix, but to notice and honor what’s already working.
For administrators, integrate LEART into existing systems. Add one LEART anchor to staff evaluation forms (e.g., “Uses wait-time ≥3 seconds after toddler vocalization”). Embed LEART language in family handouts: instead of “Your child is developing self-control,” write “We’re supporting your child’s growing ability to co-regulate big feelings—like taking deep breaths together after falling.”
LEART succeeds because it meets toddlers where they are—not as projects to be fixed, but as capable, communicative humans navigating rapid neural growth. It asks educators to slow down, observe deeply, and respond precisely—trusting that every dropped block, repeated phrase, and tear-streaked face holds meaning worth honoring.
| LEART Domain | Key Observable Indicator (Toddlers 24–36 mo) | Developmental Benchmark | Common Misinterpretation | LEART-Aligned Response |
|---|---|---|---|---|
| Learning | Tests cause-effect 3+ times with same object (e.g., pushes car down ramp, watches, repeats) | At least 2 distinct cause-effect explorations daily | “Just playing” or “not learning” | Narrate observations (“It rolled fast when you pushed hard!”); add related material (ramp with textured surface) |
| Engagement | Initiates joint attention by pointing + vocalizing + checking adult’s gaze | ≥4 episodes per hour in free play | “Shy” or “not interested” | Follow child’s lead; mirror gesture + name object (“Ball! You pointed to the ball.”) |
| Attention | Sustains focus on puzzle assembly for ≥5 minutes without adult redirection | Average 5–8 min sustained focus during preferred activity | “Short attention span” | Reduce distractions; offer one puzzle at a time; join quietly without talking |
| Regulation | Seeks adult proximity and accepts hug after meltdown, then resumes play | Recovers to baseline state within ≤60 seconds post-distress | “Needy” or “manipulative” | Offer choice (“Hug or hand squeeze?”); stay present without fixing; label effort (“You asked for help and calmed down.”) |
| Teaching | Adult uses expansion (adds 1–2 words) in ≥70% of responses to toddler speech | ≥3 expansions per 10-minute interaction | “Talking too much” | Pause 3 sec; listen fully; respond with slightly richer language (“Yes—red ball rolls!”) |
LEART does not promise perfection. It promises presence. When a toddler throws a cup, LEART invites educators to ask—not “How do I stop this?”—but “What is this telling me about Learning (testing gravity), Engagement (seeking reaction), Attention (practicing release), Regulation (overwhelmed by transition), or Teaching (my response shapes their next attempt)?” Answering that question—consistently, compassionately, and with data-informed clarity—is how we build foundations that last far beyond toddlerhood.
Real progress isn’t measured in milestones checked off, but in moments witnessed: the toddler who pauses mid-scream to watch a ladybug crawl up their arm; the caregiver who catches their own frustration and takes a breath before kneeling to eye level; the classroom where ‘behavior’ is never separated from belonging. That’s the quiet power of LEART—not control, but connection made visible, measurable, and teachable.
It’s also why LEART-trained educators report higher job satisfaction: they see growth not as a distant goal, but in the micro-shifts of today—eye contact held one second longer, a self-soothing strategy attempted independently, a shared laugh that lasts three beats past expectation. These are not small things. They are the architecture of resilience, built brick by brick, breath by breath, interaction by interaction.
For families, LEART offers translation—not jargon, but insight. When a parent says, “She hits when she’s tired,” a LEART-informed educator responds: “That’s Regulation. Her nervous system is overloaded. Let’s try a 5-minute wind-down with dim lights and heavy blankets before nap.” This bridges understanding and reduces blame, fostering partnerships where adults collaborate—not compete—for the toddler’s well-being.
LEART’s strength lies in its simplicity and specificity. It doesn’t ask educators to become child psychologists. It asks them to become skilled observers and responsive partners—equipped with clear definitions, reliable measures, and practical tools rooted in how toddlers’ brains and bodies actually develop. And in a field where turnover averages 30% annually (National Association for the Education of Young Children, 2023), frameworks that sustain educator efficacy and joy aren’t optional—they’re essential infrastructure.
Finally, LEART reminds us that toddlerhood isn’t a phase to survive—but a critical period of synaptic sculpting, where every interaction literally shapes neural pathways. Supporting Learning, Engagement, Attention, Regulation, and Teaching isn’t educational strategy. It’s biological stewardship. And it starts—not with grand plans—but with watching, waiting, and wondering, together.
The next time you see a toddler drop a block, don’t reach to pick it up. Pause. Breathe. Notice. Then ask: What is LEART showing me right now?
