• Part A: 100% women-specific schemes
• Part B: Schemes where 30–99% of benefits accrue to women
• Part C: Schemes where less than 30% of benefits accrue to women
• No Legal Backing: Gender Budgeting is an administrative exercise without statutory force
• Focus on Outlays Rather than Outcomes: It records budgetary allocations for women but does not assess whether these expenditures actually improve women's
• Difficulty in Measuring Benefits: Gender Budgeting works well for women-specific schemes, but estimating women's share in universal schemes is inherently
• Underutilisation of Funds: Allocations under several women-oriented schemes are often not fully utilised, reducing the effectiveness of Gender Budgeting
