This is relevant to anyone applying to UCLA. I emailed the graduate administrator about my GRE scores being listed as "awaiting" rather than "received", and I received this response. I hope it eases some concerns.:
The UCLA Graduate Division has informed the UCLA Psychology Department that the application status in the UCLA Graduate Division application is not yet linked to display test scores and documents received from external sources such as official transcripts, letters of recommendation, etc. Therefore, all applications submitted to the UCLA Psychology Department will not indicate whether official GRE General and/or Subject Test Scores, official TOEFL/IELTS Test Scores, official transcripts, letters of recommendation, etc. have been received by the Department.
Our Psychology Graduate Admissions Committee has begun reviewing applications. We will be contacting applicants directly if we need any missing materials such as official transcripts, official GRE General and/or Subject test scores, official TOEFL/IELTS Test Scores, letters of recommendation, etc.
