When it comes to teaching toddlers, the experts say one thing is certain: there is no substitute for a good teacher.
In fact, according to a report by the US National Center for Education Statistics, the percentage of preschool teachers who are women has risen by nearly 50 percent over the past three decades.
The report, entitled “Teaching Kids: How the Gender Gap in Teaching Is Facing New Challenges,” shows that over the course of the last decade, the number of female teachers has increased from 1.3 percent to 3.3.
In a 2016 survey by the National Center on Education Statistics , 1 in 4 American children have an English-language learner in the classroom.
The number of children with an English language learner has risen from 8.6 percent in 2014 to 11.4 percent in 2016.
The numbers are even higher when it comes in terms of students with disabilities.
According to the National School Boards Association , nearly 10 percent of all American school districts had a disability teacher in 2015, compared to just 1.4 in 1960.
Over the past two decades, the proportion of children learning at home who were able to complete a test on their own has risen, from 10.4% in 1999 to 17.1% in 2016, according the National Alliance for Learning Disabilities.
The study also shows that teachers with disabilities are not always the best candidates for their classrooms.
According the NCES report, nearly 60 percent of school district teachers have experience in other schools, compared with just 29.5 percent of those with no disabilities.
