CHRIST-CENTRED CHILD DEVELOPMENT
Your child's brain is 90% developed by age 5.
What are you doing about it?
Zedek gives you one science-backed, faith-rooted framework to track, understand, and nurture your child’s development across four pillars — from birth to age 9.

WE SEE YOU
You love your child deeply. And some days, that love comes with a quiet worry you can’t switch off.
- You're searching milestones at 11pm, and every result leaves you more anxious.
- You've downloaded multiple apps — none of them tell you what to actually do.
- Other mothers in the WhatsApp group seem to have it figured out.
- You've spent money on flashcards with no idea if any of it is working.
- School starts soon. And the quiet question: 'Is my child ready?
You don’t need another app. You need one clear framework — rooted in science, grounded in faith. That’s Zedek.
“And Jesus grew in wisdom and stature, and in favour with God and man.”
Luke 2:52 — The developmental blueprint
Four pillars. One complete picture.
Most tools track one dimension of development. Zedek tracks all four — because your child isn't just a brain. They're a body, a heart, a mind, and a soul.
Tap any pillar to explore the detail
Physical
Motor skills, body awareness, and the movement foundations that wire your child's brain for all learning.
Physical development is the fundamental operating system required for all cognitive integration. This pillar tracks fine motor skills (hand strength, precision grip, bilateral coordination), gross motor skills (locomotion, balance, vestibular processing), general coordination (crossing the midline, proprioception), sports foundations, and health and nutrition awareness.
Personal
Emotional regulation, social connection, and the attachment security that predicts lifelong resilience.
This pillar integrates 34 validated social and emotional measures — attachment milestones, joint attention, Theory of Mind, inhibitory control, emotional vocabulary, regulation strategies, growth mindset, peer relationships, and moral development. Contains critical Red Flag items (absence of social smile, eye contact, joint attention, pointing by 12 months) — primary autism screening markers weighted ×3 in our scoring model.
Potential
Cognitive growth, language, problem-solving — the thinking skills that school readiness truly requires.
Cognition disaggregated into specialised perceptual and logical components — auditory and visual perceptual skills, cognitive development (attention, working memory, executive function, planning), language and communication (emergent literacy through reading and handwriting), mathematics (concrete → representational → abstract), creative development, and scientific reasoning. Not reduced to a single "smart or not" score.
Purpose
Spiritual formation, character, and identity — raising a child who knows who God created them to be.
Dual-track system honouring diverse family values. The Christian Track (Luke 2:52) covers core beliefs, God's family, God's rescue plan, holy actions, and "What's my purpose?" The Secular/Values Track covers core values, identity and self-concept, scientific curiosity, empathy and making amends, community belonging, and personal contribution. Both tracks are validated — parents choose which aligns with their family.

ABOUT ZEDEK
Built by father and a mother who couldn’t find what their children needed.
Zedek was founded by Alton — a mechanical engineer and Leesha – a banker; parents of three in Johannesburg, South Africa. When they couldn’t find a single system that tracked their children’s development holistically, honoured their faith, and gave them clear next steps, they built one.
The result is the Zedek Tikkun Model — a proprietary ECD framework that maps child development from birth to age 9 across four interdependent pillars (Physical, Personal, Potential, Purpose), calibrated to the CDC’s 75th percentile milestone standard and grounded in the Luke 2:52 developmental blueprint.
Zedek translates the world’s best developmental research — from Johns Hopkins, Cambridge, the CDC, and Nobel laureate James Heckman — into tools and frameworks that any parent can understand and use. The science informs. The faith anchors. The parent leads.
