I have a niece who is adopted. She had a hard life until she was adopted at age 9. She was way behind in school and had to be kept back in 5th grade. However, my sister is one of those Tiger Moms and demanded things like reading every day for at least 30 minutes. My niece is now in 7th grade and is getting straight As and reads at a high school level. My niece is also Hispanic and every bit as smart as the other kids in her class. The main difference is her household now has a culture that place a high value on education.
