Transparency & Methodology

Safety Score Methodology

Every toy receives a SafeNest editorial Safety Score from 0 to 100 based on four weighted factors. A higher score represents a more favorable SafeNest editorial assessment of the information available at the time. It does not measure absolute safety, certify a product, or guarantee that a product is hazard-free.

SafeNest does not perform physical or laboratory testing, does not certify, guarantee, approve, or endorse products, and does not independently verify every manufacturer claim. Scores never replace the manufacturer's instructions or an official recall notice.

Formula: Safety Score = (Material Safety × 0.30) + (Choking Risk × 0.30) + (Recall History × 0.20) + (Certification Presence × 0.20)

Evidence status and evidence confidence

A score on its own cannot tell you how much is actually known about a toy. So alongside every score we record how well each safety factor is supported, and publish an overall evidence confidence rating.

SafeNest reviews publicly available manufacturer information, certification claims, product specifications, age guidance, and CPSC recall records. We do not physically or laboratory test products, independently verify every manufacturer claim, or certify products.

What each evidence status means

How editorial scores and evidence confidence relate

Editorial scores reflect SafeNest's assessment of publicly available product information. Evidence confidence separately describes how well that information is supported. Evidence confidence does not currently modify the editorial score.

This means a high editorial score can appear alongside Medium or Low evidence confidence. A high editorial score with Low or Medium evidence confidence should be interpreted cautiously, and a high score is never proof that a product is objectively safer.

How evidence confidence is derived

• High — important claims are predominantly supported by accessible documentation or official sources.
• Medium — important claims are mostly manufacturer-reported.
• Low — important claims rely heavily on retailers, secondary sources or missing information.
• Insufficient — the available information cannot support a meaningful assessment, so we show no precise score.

How missing and conflicting evidence are handled

• Missing information is never treated as proof of safety. It lowers evidence confidence for that factor.
• Conflicting information is surfaced as “sources conflict” rather than silently reconciled, and it lowers confidence. Conflicting or missing evidence cannot produce High confidence.
• A certification claim is not a certification document. We record who reported it and whether supporting documentation was located.
• When the supporting information is too thin overall, we show “Insufficient evidence” rather than inventing a precise score.
• SafeNest does not perform physical or laboratory testing, and these scores are not professional product-safety opinions. Rodrigo and Vanessa are parents, not credentialed product-safety professionals.
• Affiliate relationships never influence scores. Corrections can be submitted through our contact form.
• The manufacturer's instructions and official recall notices always take precedence over anything on this site.

Certification claims

We do not confirm that a toy complies with a standard. We record which certifications are reported and label each claim as supported by accessible documentation, manufacturer-reported, retailer-reported, not found, or unclear.

Recall checks

We check products against publicly available CPSC recall information and display the date of the latest recorded check. Always confirm with the official CPSC database. A recall is only attached to a review when the match is unambiguous; uncertain matches are held for human review rather than published.

Scores are editorial assessments. They are not certifications, guarantees, or approvals, and they are not a substitute for the manufacturer's instructions or an official recall notice.

Development Score Methodology

The Development Score (0–100) evaluates how well a toy supports a child's developmental growth across three dimensions.

Formula: Development Score = (Motor Skills × 0.40) + (Cognitive Skills × 0.35) + (Sensory Engagement × 0.25)

Data Sources

Our assessments draw from multiple authoritative sources:

• CPSC Recall Database — U.S. Consumer Product Safety Commission official recall listings
• ASTM F963 Standards — Standard Consumer Safety Specification for Toy Safety
• EN-71 Standards — European toy safety standards for mechanical, physical, and chemical properties
• Manufacturer Disclosures — Published material safety data sheets and certifications
• Developmental Psychology Research — Peer-reviewed studies on play and child development
