Admissions Requirement

Hi. my sister will be applying to GSMST for 9th grade and I had a couple of questions about the admission requirement. What is the Enhanced Algebra requirement mean? It looks like GCPS changed some of the naming since I was in middle school but is Enhanced Algebra the equivalent of taking Algebra 1 in 8th grade? I remember the common pathway is that 8th graders typically take Pre-Algebra and then Algebra 1 in 9th grade or a honors pathway would be Algebra 1 in 8th graders then Geometry in 9th grade.

so is enhanced algebra the equivalent of taking 9th grade algebra 1 in 8th graders?

any help would be appreciate.
