intensity,
and
duration
were
considered.
The
findings
indicate
that
the
vast
majority
of
recent
early
education
and
care
programs
had
considerable
positive
short-‐term
effects
and
somewhat
smaller
long-‐term
effects
on
cognitive
development
and
that
in
relative
terms
children
from
socioeconomically
disadvantaged
families
made
as
much
or
slightly
more
progress
than
their
more
advantaged
peers.
Despite
benefits,
early
childhood
education
and
care
cannot
entirely
compensate
for
developmental
deficits
due
to
unfavorable
learning
conditions
in
disadvantaged
milieus.
