OPINION
Opinion by Justice ROSS.Joseph Noel Seals appeals the order dismissing his petition for divorce from his wife, Jacklyn Seals. Jacklyn filed no brief and does not contest the dismissal of her counterclaim. Joseph contends the trial court abused its discretion and denied him due process of law by dismissing his case for want of prosecution.
Joseph, a federal prisoner, filed an original petition for divorce pro se on July 13, 2000, on the grounds that the couple had ceased living together in 1983 and the marriage had become insupportable. His petition stated that there were no children born or adopted of the marriage and that “there is no division of the estates or valuable property in this suit.” He requested the court to compel his wife to change her name. Six days after Joseph filed his original petition, he filed a letter with the court advising of his incarceration and inability to appear in person, but stating, “If it is extremely required you shall then contact the institution’s Warden here at FCI Texarkana,.... ” Joseph further stated, “Consequently, due to the aforementioned, the Decree of Divorce shall be issued in absentia.” On July 31, 2000, Jacklyn filed her original answer, in which she entered a general denial and a counterclaim for divorce, and requested the court to make an equitable division of the parties’ estate.
Almost a year later, June 29, 2001, Joseph filed another letter with the court. In this letter, he specifically requested his case be expedited and again advised the court of his inability to attend any hearings regarding his divorce unless the court “request this institution’s Warden to transfer me to your Court or county.” Less than four months later, on October 23, the *873court clerk issued a notice to both Jacklyn, through her counsel, and to Joseph of the court’s intent to dismiss the case for want of prosecution pursuant to Rule 165a. The notice stated the dismissal hearing was set for November 5, 2001. On the date of the dismissal hearing, Joseph filed a document entitled “Waiver of Citation,” agreeing “that the cause may be taken up and considered by the Court without further notice to me,” and again notifying the court he was incarcerated and stating the petition for divorce should be granted in ab-sentia. The court dismissed his case for want of prosecution the next day.
Joseph contends the trial court abused its discretion when it dismissed his divorce case under Rule 165a. Rule 165a provides that a judge may dismiss a case for want of prosecution when any party seeking affirmative relief fails to appear for any hearing or trial of which the party had notice or when the case is not disposed of within the time standards promulgated by the Texas Supreme Court under its Administrative Rules unless, at a dismissal hearing about which the parties are provided adequate notice, good cause is shown for the case to be maintained on the docket. Tex.R. Crv. P. 165a(l), (2).
A party must be provided with notice and an opportunity to be heard before a court may dismiss a case for want of prosecution under either Rule 165a or its inherent authority. See Tex.R. Civ. P. 165a(l) (“Notice of the court’s intention to dismiss and the date and place of the dismissal hearing shall be sent by the clerk to each attorney of record,.... ”); Villarreal v. San Antonio Truck & Equip., 994 S.W.2d 628, 630 (Tex.1999); Gen. Elec. Co. v. Falcon Ridge Apartments, Joint Venture, 811 S.W.2d 942, 943 (Tex.1991); Gutierrez v. Lone Star Nat’l Bank, 960 S.W.2d 211, 214 (Tex.App.-Corpus Christi 1997, pet. denied) (requiring notice for dismissals under Rule 165a); see also Callahan v. Staples, 139 Tex. 8,161 S.W.2d 489, 491 (Tex.1942) (requiring notice for dismissals under the court’s inherent power). The failure to provide adequate notice of the trial court’s intent to dismiss for want of prosecution requires reversal. See Donnell v. Spring Sports, Inc., 920 S.W.2d 378, 386 (Tex.App.-Houston [1st Dist.] 1996, writ denied); Davis v. Laredo Diesel, Inc., 611 S.W.2d 943, 946 — 47 (Tex.Civ.App.-Waco 1981, writ ref d n.r.e.). Dismissal may only be granted on the basis stated in the notice of dismissal. Villarreal, 994 S.W.2d at 632.
The notice of dismissal in this case specifically stated:
Pursuant to Rule 165a, T.R.C.P., the court has set the above case for a dismissal hearing:

The court will dismiss the case for want of prosecution at his [sic] time unless an attorney or pro se party appears in person and shows good cause for maintaining the case on the docket.
Under Rule 165a, the trial court may dismiss the case for two reasons: the failure of a party to appear at a hearing or trial, or for noncompliance with time standards. Because the trial court did not specify under which section it dismissed the case, we will review the dismissal under both. And because the dismissal order does not specify the reason for dismissal, it will be affirmed on appeal if any proper ground supports the dismissal. Shook v. Gilmore & Tatge Mfg. Co., 951 S.W.2d 294, 296 (Tex.App.-Waco 1997, pet. denied).
The standard of review for dismissal for want of prosecution is abuse of discretion. See Coleman v. Lynaugh, 934 S.W.2d 837, 838 (Tex.App.-Houston [1st Dist.] 1996, no writ). The test for abuse of *874discretion is whether the trial court acted without reference to any guiding rules or principles or, equivalently, whether, under all the circumstances of the particular case, the trial court’s action was arbitrary or unreasonable. Koslow’s v. Mackie, 796 S.W.2d 700, 704 (Tex.1990). The trial court may consider the entire history of the case, including: 1) the length of time the case was on file; 2) the extent of activity in the case; 3) whether a trial setting was requested; and 4) the existence of reasonable excuse for the delay. Cf. King v. Holland, 884 S.W.2d 231, 237 (Tex.App.-Corpus Christi 1994, writ denied); City of Houston v. Malone, 828 S.W.2d 567, 568 (Tex.App.-Houston [14th Dist.] 1992, no writ).
At the time the notice of the court’s intent to dismiss was sent, no hearing had been set in the case, so Joseph had never failed to appear. Joseph did not appear at the hearing, but after the notice was sent, he filed a ‘Waiver of Citation,” in which he reminded the court of his incarceration and again requested the trial court to grant the divorce in absentia. This document, along with Joseph’s earlier correspondence requesting an expedited trial setting and informing the court of his incarceration, and making requests which should have been construed as requests for a bench warrant, sufficed to inform the court of his inability to attend the dismissal hearing and show good cause for his failure to appear at the hearing. To the extent the trial court dismissed the case based on Joseph’s failure to appear at the hearing, the trial court abused its discretion.
The second way a trial court may dismiss a case under Rule 165a is for failure of a party to comply with the time standards set by the Texas Supreme Court. Rule 165a(2) states: “Any case not disposed of within time standards promulgated by the Supreme Court under its Administrative Rules may be placed on a dismissal docket.” Tex.R. Civ. P. 165a(2). Rule 6 of the Texas Rules of Judicial Administration promulgated by the Texas Supreme Court provides that:
[J]udges of the county in which cases are filed should, so far as reasonably possible, ensure that all cases are brought to trial or final disposition, in conformity with the following time standards:

Within 6 months from appearance date or within 6 months from the expiration of the waiting period provided by the Family Code where such is required, whichever is later.
Tex.R. Jud. Admin. 6(c)(1), reprinted in Tex. Gov’t Code Ann., tit. 2, subtit. F app. (Vernon 1998).
Joseph filed his petition for divorce on July 13, 2000. On July 19, 2000, he filed a letter with the court advising of his incarceration and stating, in effect, that, if his presence in court was required, then a bench warrant should be' issued. Jacklyn filed her answer on July 31, 2000. On June 29, 2001, Joseph sent his next correspondence to the trial court, advising the court that time had lapsed since the filing of his divorce petition and that no disposition had yet occurred. He specifically requested the trial court to expedite the petition for disposition. On October 23, 2001, the trial court notified both Joseph and Jacklyn the case would be dismissed if the parties did not appear at a hearing set for November 5, 2001, and show good cause for the case to be maintained on the docket. On November 5, Joseph filed a document stating for the second time that, because of his incarceration, the divorce should be granted in ab-sentia. The trial court dismissed the case *875on November 6, 2001, approximately fifteen months after Jaeklyn’s appearance. After the trial court dismissed the case, but within the court’s period of plenary power, Jacklyn also filed a “Waiver of Citation,” agreeing the case could be taken up and considered without further notice to her.
Although Joseph made no formal request for a trial setting during the first six months, he filed a letter with the court eleven months after Jaeklyn’s appearance requesting that the court expedite his divorce. Less than four months later, instead of granting Joseph’s request for an expedited trial, the court placed the case on the dismissal docket. After the case was set on the dismissal docket, Joseph filed a document again requesting the divorce be granted in absentia.
Rule 6 of the Rules of Judicial Administration requires judges to ensure that cases are brought to trial or disposition. Further, the trial court may, on the court’s own motion and with reasonable notice to the parties, set contested cases for trial. Noncontested cases may be tried or disposed of at any time whether set or not, and may be set at any time for any other time. See Tex.R. Civ. P. 245.
After the court had failed to set this case for trial on its own motion for more than fifteen months, and after receiving a request from one of the parties for an expedited trial setting only four months earlier, it was an abuse of discretion to dismiss this case for noncompliance with the time standards. While the court still had plenary power over this case, it knew both parties had waived citation and requested the court to grant the divorce. Both parties want the divorce. To dismiss this case, requiring the parties to file it again, is a waste of judicial and economic resources. The record clearly shows good cause why the court should not have dismissed this case for want of prosecution.
We reverse the trial court’s order of dismissal and remand the case for further proceedings.
