How SkolScore Rates Schools: Our Methodology Explained

Every parent deserves to know exactly how a school rating is calculated before trusting it with one of the most important decisions of their child's life. The SkolScore rating is a single number between 1 and 10, but it is built from hundreds of verified data points across five distinct pillars. This article walks you through every component of our methodology so you can evaluate any school on SkolScore with full transparency.

The Five Pillars at a Glance

Pillar	Weight	Primary Data Source
Academics	30%	Board results, board type baseline
Parent Reviews	25%	Structured SkolScore parent surveys
Infrastructure	20%	UDISE+ facility reports
Teacher Quality	15%	UDISE+ staffing and qualification data
Safety	10%	UDISE+ physical infrastructure data

The final SkolScore rating is a weighted average of these five pillar scores, each normalized to a 0-10 scale before combining. A school must have sufficient data across at least three pillars to receive a published score. Schools with thin data show an "Insufficient Data" label rather than a misleading number.

Pillar 1: Academics (30%)

Academics carries the largest weight because it is the most direct measure of what a school is there to do: educate children.

Board results

For CBSE and ICSE schools, we pull Class 10 and Class 12 pass rates, distinction percentages, and subject-level performance from board result data. A school where 95% of students pass Class 12 and 40% score distinctions rates significantly higher than one where 70% pass and distinctions are rare.

For state board schools, we use available SSLC result data published by state education departments. Where board-level granularity is unavailable, we use school-reported enrollment and promotion data from UDISE+.

Board type baseline

Different boards carry different academic rigor profiles. ICSE and IB schools receive a slight upward baseline because of the documented breadth of their curricula. This is a small adjustment, roughly 0.3 to 0.5 points, not a blanket premium. A poorly performing ICSE school will still score lower than a strong state board school.

What academics does NOT include

We deliberately exclude fee levels, alumni brand names, and "percentage of students who cleared JEE/NEET." These metrics correlate more with the student intake profile than with what a school actually does for a child. A school that takes only toppers and sends them to IITs is not necessarily a better school than one that takes average students and meaningfully raises their outcomes.

Pillar 2: Parent Reviews (25%)

Parent experience is the second-largest pillar because no government dataset captures what daily school life actually feels like for a child.

How reviews are collected

Parents who have children currently enrolled or recently graduated submit structured ratings on SkolScore. We ask for numerical scores (1-5) across six sub-dimensions: teaching quality, communication with parents, safety and discipline, extracurricular opportunities, homework load balance, and value for fees. Each sub-dimension is then aggregated and converted to the 0-10 pillar scale.

Bayesian averaging

A school with 3 five-star reviews should not outrank a school with 200 balanced reviews. We apply a Bayesian average that pulls ratings toward the city-wide mean when the review count is low. A school needs at least 15 verified reviews before its parent review score carries full weight. Below that threshold, the score is blended toward the Bangalore or Hyderabad average.

Fraud prevention

Reviews are tied to verified parent accounts. We flag and quarantine sudden review spikes (more than five reviews in 48 hours for any school) for manual review. Schools cannot submit reviews on behalf of parents, and we do not accept reviews from email domains that match the school's own domain.

Pillar 3: Infrastructure (20%)

A school's physical environment shapes learning outcomes in measurable ways. UDISE+ collects detailed facility data annually from every school in India. We use this data directly.

What we measure

• Computer availability: number of functional computers per 100 students
• Library: presence and size of a school library
• Science labs: availability for middle and senior secondary classes
• Sanitation: number of functional toilets, separated by gender
• Drinking water: type and availability of clean drinking water
• Electricity: reliable power supply including solar or backup

Each facility is scored on a 0-1 scale and the infrastructure pillar score is the weighted average across all facilities. A school with a well-equipped computer lab but no functional library does not score the same as one with both.

Urban vs. rural adjustment

Infrastructure expectations differ by context. A government primary school in a rural block is evaluated against peers in similar contexts, not against private CBSE schools in Koramangala. SkolScore applies a peer-group normalization so that rural and lower-income schools can still earn high infrastructure scores relative to their context. The full 1-10 SkolScore, however, is an absolute rating, not a contextual one.

Pillar 4: Teacher Quality (15%)

Teachers are the single most studied factor in student outcomes. Our teacher quality pillar uses two primary signals from UDISE+ data.

Student-teacher ratio

We calculate the ratio of total enrolled students to sanctioned teaching staff. The national UDISE+ benchmark for a well-staffed school is 30:1 or better at the primary level and 35:1 at the secondary level. Schools significantly above these ratios receive lower scores on this sub-metric.

Teacher qualifications

UDISE+ reports the percentage of teachers who hold a professional teaching qualification (B.Ed or equivalent). Schools where more than 90% of teachers are formally qualified score at the top of this sub-metric. Schools with high proportions of unqualified or part-time staff score lower.

What this pillar cannot capture

We are aware that qualification and ratio are proxies, not direct measures of teaching quality. A brilliant teacher with a non-standard background will not show up as "better" in this data. This is why parent reviews (which capture teaching quality as a lived experience) carry a higher weight than this pillar. We are actively exploring how to incorporate structured classroom observation data as that becomes available.

Pillar 5: Safety (10%)

Safety carries the smallest weight not because it matters less, but because the variance across urban schools in Bangalore and Hyderabad is lower. Most urban private schools meet basic safety thresholds. Where they do not, the impact on the score is significant.

Safety indicators

• Boundary wall: presence of a complete boundary wall or compound
• CCTV: presence of surveillance cameras in key areas (self-reported to UDISE+)
• Ramps: availability of ramps for children with mobility needs
• Toilet adequacy: ratio of girls' toilets to female enrollment (a proxy for personal safety and dignity)
• Drinking water quality: access to clean, tested water

A school missing a boundary wall in an urban area, for example, loses roughly 0.4 points on its final score. A school with no girls' toilets at all would see a more significant penalty.

A Real Example: How Scores Combine

Consider a hypothetical school, Greenfield Academy, with the following pillar scores:

Pillar	Raw Score (0-10)	Weight	Weighted Score
Academics	7.8	30%	2.34
Parent Reviews	6.5	25%	1.63
Infrastructure	8.2	20%	1.64
Teacher Quality	6.0	15%	0.90
Safety	9.0	10%	0.90
Final SkolScore			7.41

This school would display a SkolScore of 7.4. A parent looking at this breakdown can immediately see that teacher quality is the relative weakness, even though the school scores well on infrastructure and safety. That kind of transparency is exactly what we designed the breakdown view to provide.

What SkolScore Does Not Rate

Being transparent about our methodology includes being clear about its limits.

Extracurricular excellence: A school that has produced national-level athletes or musicians will not score higher on that basis alone. Parent reviews partially capture extracurricular satisfaction, but we do not have structured data on sports facilities, arts programs, or clubs.

Fee value: We do not factor fees into the SkolScore rating. A school charging Rs. 3 lakh per year and a school charging Rs. 30,000 per year can both score 8.0 if they deliver on the same five pillars. A separate "value for fees" metric is available on each school profile page.

Admissions selectivity: We do not reward schools for being hard to get into. Selectivity is a school's choice, not an educational outcome.

School culture and values: No data source yet captures whether a school fosters intellectual curiosity, emotional resilience, or genuine community. We rely on parent reviews to partially surface this through open-text comments, but it is not a scored component.

How Often Scores Update

UDISE+ data is released annually, typically in the second half of the calendar year. When new UDISE+ data becomes available, we reprocess all school scores within 30 days of the official release. Parent review scores update in real time as new reviews are verified and published. This means a school's SkolScore can change, and change meaningfully, from one year to the next.
