When a PhD program asks for academic transcripts, are they referring to university-level transcripts only or also earlier transcripts?

I have some questions regarding graduate admission (PHD) in us university. The guidelines stated on the maximum university websites are that they require academic transcripts. My question is that, are the Bachelor of Science (BSc) and Masters of Science (MSc ) transcripts only? or I will have to send all the academic records(verified) from the childhoods?
