This may be a false belief, as the U.S. Department of Education, in a factsheet dated July 2009, describes Statewide Longitudinal Data Systems which have been funded through grants since 2005:
The Recovery Act competition requires that the data systems have the capacity to link preschool, K-12, and postsecondary education as well as workforce data. To receive State Fiscal Stabilization Funds, a state must provide an assurance that it will establish a longitudinal data system that includes the 12 elements described in the America COMPETES Act, and any data system developed with Statewide longitudinal data system funds must include at least these 12 elements. The elements are:

1.An unique identifier for every student that does not permit a student to be individually identified (except as permitted by federal and state law);
2.The school enrollment history, demographic characteristics, and program participation record of every student;
3.Information on when a student enrolls, transfers, drops out, or graduates from a school;
4.Students scores on tests required by the Elementary and Secondary Education Act;
5.Information on students who are not tested, by grade and subject;
6.Students scores on tests measuring whether they're ready for college;
7.A way to identify teachers and to match teachers to their students;
8.Information from students' transcripts, specifically courses taken and grades earned;
9.Data on students' success in college, including whether they enrolled in remedial courses;
10.Data on whether K-12 students are prepared to succeed in college;
11.A system of auditing data for quality, validity, and reliability; and
12.The ability to share data from preschool through postsecondary education data systems.

...These data systems will capture data on students from one grade to the next...
