Hi! I think you mean the OSKAR test (Online Screening for Keen and Advanced Readiness), it's really helpful if you're wondering kung ready na ang bata for school or if may developmental concerns, so I'd suggest asking your pediatrician kung appropriate na para sa age ng anak mo at ano talaga ang gusto mong malaman. A few of us mums had our kids screened around 3-4 years old para ma-assess ang speech, social skills, at all-around development, pero depende talaga sa pediatrician mo kung kailangan or recommended, kaya mas maganda direct consultation na lang para personalized advice
